Answer 1

Hey ! .

No. of girls = 55
No. of boys=( 3/2 ) 55
➖➖➖➖= 82

Total no. of boys and girls = 55 + 82
➖➖➖➖➖➖➖➖➖= 137

Answer 2

Step-by-step explanation:

Let the number of girls be x

So the no. of boys = 3/ 2  x

Total no. of students = no. of girls + no. of boys

55 = x + 3 /2 x

55 = / 1  +  3/ 2

55 =  2×  /2×1  +  3 /2

55 =  5 /2

2 × 55 = 5x

110 = 5x

= 110/ 5  = 22

Therefore the no. of girls = 22

And the no. of boys = 3 /2 × 22 = 33
