Question

In a class of 40 students three upon five of the total number of students are girls how many students of the class are boys​

Answer 1

Step-by-step explanation:

Total no. of students=40

No. of girls = 3/5th of 40

No. of boys= 1-3/5 = 2/5th of 40

Therefore, no. of boys = 2/5 x 40

=16

Answer 2

Answer:

16

Step-by-step explanation:

if

$x = 40 \\ then \: \frac{3}{5} x = 40 \times \frac{3}{5} = 24 \\ no \: of \: girls \: = 24$

then no of boys = 40-24 =16
