The meaning of the percentage.
Excuse me, how much is this?
Let's see, it has a 25% discount, so it's worth 15 pesos.
Fantastic, I'll take it.
I love the little girls.
What is your brother doing?
He has sold more than any of us, despite the fact that his merchandise is the most expensive.
I don't know, are any of them ugly?
This is what I call a beautiful bird cage. How much is it worth?
Let's see, it has a 20% discount and its price list is 15 pesos, so it's worth 12 dollars.
Oh, yes? Sold.
Now he comes with the bird included.
I'm afraid it's the best price I can make.
Forget it.
It's worth 4, but with a 50% discount I'll leave it at 2.
Okay, Brenda, what's your secret?
Tell us how you sold more than we did.
There's no secret. I put most of the merchandise on offer with discounts of 5 to 50%.
So you raised the prices from 5 to 50%?
Correct. Well, almost all of them.
Except this one, of course.
The real price or nothing.
You should have told me that's the first thing you should have put on offer.
It's ugly. It's very ugly.
Oh, that little sister.
Brenda, putting most of this merchandise on offer is a bit of a headache.
You'll get less money this way.
Maybe, but you haven't said anything yet.
You prefer to have a part of something that is 100% nothing, you know?
Really?
Believe me.
Let's see here. Sandy's things that are worth a penny aren't selling very well, right?
Yes.
So let's reduce the prices and see what happens.
You say we reduce the merchandise by 5 to 10%?
Yes.
Percentage, what?
Come on, Sandy. At least try it.
But percentage?
Please, Sandy. You have problems with percentages.
Like many people, Jan. Why don't you understand what percentage means?
And when percentages aren't understood, things get complicated.
Percentages are everywhere, on TV, on radio, on advertising ads like
our burgers are 25% bigger than theirs, or in stores like
prices have increased by 4%.
Percentages are used a lot in advertising because they give a sense of proportion.
An idea of how big or better a product is for a statistic means something we can get,
which is 25% bigger or better than another article.
I've asked something more about percentages.
Do I make a better purchase if I buy something that's worth two pesos with a 50% discount,
or is it better to buy an object of one peso with a 50% discount?
Well, 50% or half of two pesos is more money than half of one peso,
but 50% is 50%. The discount percentage is always the same.
Let me think about it.
Speaking of differences, let's go back to the sales
in Mexico State.
The answer was 100%.
That's one more pin.
100 cents.
So 100% would be 100 cents.
Each penny would be 1%.
So how much would 30% of a dollar be?
30%?
Would be 30 cents.
Correct.
So if you marked that toy with 30% discount, how much would it cost?
30 cents, correct?
Not enough.
If this is 100% in total, or 100 cents, and 30% discount is 30 cents, that gives you an idea of what the total price is.
In that case, a penny.
So the cost would be 70 cents, and the rest 30 cents, right?
Correct.
Okay, now tell me, how much does that coffee cup cost with a 60% discount?
Well, it's a penny.
So what does that cost?
100%.
But if we took out 60% of the price, it would be 60 cents.
So the final cost would be 40 cents, right?
You got it.
You also have a client.
Look at this, the prices went down.
Yes, that's right.
This coffee cup has a 40% discount, and this 25%, and this 50%.
I'll take them all.
I can't resist the offers.
I can't.
So what's the result?
Yes, tell the other guys.
Did you buy the coffee cup or not?
Yes, I did.
Come on, Patty, why don't we lower some prices?
At least to see what happens.
Yes, Patty, it would be better if you did.
Okay.
It seems that things are getting interesting, but it's important that Brenda understands how to do the percentage, otherwise she won't do well in sales.
Or they'll get the prices wrong.
Correct. Anyway, it was good when Sandy told you that the percentage was always going to be 100.
Now let's see what 100% means.
Let's say we have a band with 100 musicians.
100% of the band means there are 100 people.
Let's say one person would be 1% of the band.
What would be 75%?
That's right.
75 members of the band of 100.
Since 75% means 75 of 100, it's written 75% or 75 over 100.
Or we write it with a decimal number, which is the only way to work with a percentage in a calculator.
Anyway, we'll understand the percentages better if we convert them conveniently to 100.
Like the group of the table of one peso.
Correct. But what if we take the amount you work with, say 250 or 75 or 50?
Even so, can you calculate the percentage here?
It's useless.
What?
It was a joke.
By the way, you can calculate, Rose.
Let's say you have a band with 50 musicians.
100% of the band would be 50 musicians in total.
But what if it would be 50% of the total?
Well, I suppose you could think of 50 over 100, which would be equal to half.
So 50% of the band would be 25 musicians.
25 over 50 is also half.
Now, do you understand what this means?
It shows the relationship of a part of a total.
And the total unit of something is 100%.
And it's not necessary to have 100 things to make a percentage.
You can calculate it with any number.
Correct.
Yes, we have seen the percentage in the table of one peso.
But what if the guys from the table of five pesos try to use it?
Can you calculate how much would be 50% of five pesos?
50 cents? Does it make sense what you say?
Well, 50% was 50 cents in the table of one peso.
Yes, but that's the table of five pesos.
It's worth five times more.
Remember that in the table of one peso, 100% was 100 cents.
And 50% was 50 cents.
But now we have five pesos.
And we have to calculate how much is the 50% discount for each object that is worth five pesos.
So if 50% of one peso is 50 cents, we have to calculate five times 50 cents.
So, what would it be?
Two fifty.
You did it.
It was easy.
Hi guys, how's it going?
Very good.
Do you see something you like?
Really? Yes, over there.
That?
That's ideal for my collection.
The funny thing is that I don't see that I have the discount tag.
Because it has no discount, it's worth 25 pesos.
25 pesos? That's more than I can pay.
Excuse me.
Are you crazy? Are you putting it on sale?
No, absolutely not.
We'll get back to those folks in a minute.
But first, you feel inside the core of a very special feeling.
Believe it or not, percentages are often found in sports, especially in basketball.
So, we're taking a break with exciting action where we'll talk,
no less than with one of the former members of the Angelic Layton, Tick Hurd.
Thank you.
How are percentages used in basketball?
Well, it's very simple.
They can be used in many ways.
For example, let's say a teammate is on the free kick line.
And Tick means he's been there eight times tonight and has done four kicks.
What would be the percentage?
Fifty percent.
Look, if a new kid didn't score at least 70% of the free kicks, he's not a good shooter.
If he scores 80% of the kicks, he's very good.
Byron Scott, who played for the Angelic Lakers, scored an average of 89.9%.
Which made him the third in the league.
The best percentage was James Wolf.
James always said that the highest percentage of goals in NBA history.
If a player throws the 48% it's good.
If one does it in a 50% it's very good.
And if they do it in a higher percentage, frankly, it's a great goal.
Wolfie has scored 63% of the goals.
The percentages I told you about are very important.
If I say a kid scored five out of nine, that doesn't matter.
What I want to know is, is Tick good or bad?
Obviously, he would be better than a 50%.
Five out of nine, five out of ten, he would be a 50%.
Do you know what I did?
I have everything in a book.
For example, up to there I can get to number 78 or 27.
27 out of 78 goals I scored last month, that is, 34.6%.
And I can do the same while watching the game.
People think I'm smart, but I have my own limits.
So, what do you think about the last of 17?
What do you think about putting those things in a box?
I don't know, it gives them results, whatever else.
I give up.
How much do we get off?
Five percent.
Only five percent?
Okay, that's a small discount.
We get five percent off the total price.
That means that the customers will pay the risk.
That's 95% off the total price, right?
90% of 10 pesos is nine pesos.
10% of 10 pesos is one peso.
But we only need to find five percent of half of that,
which would be 50 cents.
So the final cost would be 9.50.
So if I take 25% off the total price,
I only have to calculate 75% of 10
to find the price of the offer, right?
That's it.
75% of one peso is 75 cents.
If I multiply it by 10, it would be 7.50.
That's all.
That's a lot faster.
I see you put the offer in that table.
Tell me the price.
50 cents per car.
Okay.
Olya, is this on sale?
Yes, it is.
But I can't believe the price it has.
25? There must be a mistake.
The price is 25 pesos, as I told you.
I'm not going to put it on sale.
Take it?
What will I do?
The offer?
The offer would say no.
Its price is ridiculously low.
This is a strange and valuable object.
I consider it should not cost less than 50 pesos.
Do you accept it?
Yes.
Thank you.
Thank you.
No.
It's me who should thank you.
It's 50 pesos?
That's why?
Come on.
That's what I told you.
It's a good offer.
It's important to know how to get a percentage.
They are not difficult to do.
When you understand them...
Just remember that you always have to be part of a total.
Think about it this way.
Only 50% of this team.
And me, the other 50%.
We are all part of the 100%.
Solve it.
