Question

If the ratio of boys to girls in a class of 50 students is 3:2, what is the number of boys in the class?​

Answer 1

Answer:

30 boys

Step-by-step explanation:

The ratio indicates that for every 3 boys there are 2 girls

first add the two numbers

3+2 = 5

now take this as the denominator and substitute as :

3/5 : 2/5

therefore ,

3/5 of the boys + 2/5 of girls = 50

3/5 of 50 = 30

2/5 of 50 = 20

Therefore there are 30 boys and twenty girls
