# If the ratio of boys to girls is 3:2 and there are 25 students in a class, how do you make equal ratios to show how many students in the class are boys and how many are girls?

##### 1 Answer

#### Answer:

The explanation is much longer than doing the mathematics.

The ratio of 15 boys to 10 girls is equivalent to the ratio of 3:2

#### Explanation:

Consider the starting point:

We have 3 boys and 2 girls. This gives a total count of 5

So we need to see how many lots of 5 will fit into 25.

5 lots of 5 gives 25

So we have 5 lots of the ratio 3:2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

5 lots of 3:2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Write the ratio in fractional form

It does not matter in this case which we put on the top. I chose:

Multiply a value (or system) by 1 and you do not change the value. However, 1 comes in many forms.

The ratio of 15 boys to 10 girls is equivalent to the ratio of 3:2
