Well, for ratio problems like this, here’s what you do:

1. Add the numbers in the ratio together:

3 + 4 = 7

2. Divide that number by the quantity given:

238 / 7 =
34

3. Multiply each part of the ratio by the quotient:

4 x 34 = 136

3 x 34 = 102

102 + 136 = 238
4. Answer the problem using the information you just found:

The ratio of girls to boys in the junior class is 102 : 136.
