Answer:
The numbers of boys in one grade are 60 .
Step-by-step 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 .
