There are 238 juniors in a school. The ratio of girls to boys is 3 : 4. How many girls. Boys?

There are 102 girls and 136 boys and 238 juniors

Step-by-step explanation:

girls: boys: total

3 4 7

Multiply by x

3x 4x 7x

The ratio has to stay the same

We have 238 juniors. That is our total

238 = 7x

Divide by 7

238/7 = 7x/x

34 = x

Now we can figure out how many girls and boys since we know x

girls: boys: total

3x 4x 7x

3 (34) 4 (34) 238

102 136 238

There are 102 girls and 136 boys and 238 juniors
