Answer:

The numbers of boys in one grade are 60 .

Explanation:

As given

In one grade of 150 students .

The ratio of boys to girls is 2:3.

Let us assume that the scalar multiple of boys and girls be x.

Thus number of boys = 2x

Number of girls = 3x

Than the equations becomes

2x + 3x = 150

5x = 150

x = 30

Thus number of boys = 2 × 30

= 60

Therefore the numbers of boys in one grade are 60 .

Hope this helped
