Section 1
Finding a percentage OF a quantity

Ronaldo won 80% of the games he played.
If he played 35 games, how many games did he win?
80% of 35 is what?
This question deals with finding a percentage of a quantity when you already know the quantity and the percentage. The steps are as follows.
Put the percentage over 100 and then multiply it by 35 (the quantity)
80/100   x 35/1

We can then simplify this to 8/10 x 35/1
Multiply the 2 fractions so we can get =   280/10
And now, divide 280 by 10 which equal 28.

Now, first of all we want to find out what percentage of the class are girls. But why don’t we find out what percentage of the class are boys first?

So, (Boys)
We want to find out what percentage is 16 (amount of boys in the class) is OF 28 (total amount of students in the class)

First step:
You need to put the number that you want to find out (number of boys) OVER the total number (number of student’s altogether)

Second step:
Multiply it by   100/1
16/28   x   100/1
Then all you have to do is multiply and cancel. So lets multiply straight across without cancelling.

Multiply the numerators together (top numbers)
Multiply the...
