Question

Find the rational number of boys 7x and 5x girls

Answer 1

Answer:

48

Step-by-step explanation:

Let us assume the number of boys and the number of girls is 7x and 5x.

According to the given data in the queustion,

7x = 5x +8

Transposing 5x to the LHS we get

7x - 5x = 8

2x = 8

Dividing both sides by 2x = 4

Hence,

The number of boys = 7 x 4 = 28

The number of girls = 5 x 4 = 20

So, total number of students = 20 + 28

= 48
