7

Step-by-step explanation:

Answer 2

Let the number of girls be x, then the number of boys as given: 6/7 of girls

Number of girls = x

Number of boys = 6/7 of x

= 6x/7

Total number of students given: 52

hence,

No. of girls + No. of boys = 52 students

$x + \frac{6x}{7} = 52$

$\frac{x}{1} + \frac{6x}{7} = 52$

LCM of 1 and 7 is 7

$\frac{7x + 6x}{7} = 52$

$\frac{13x}{7} = 52$

$x = 52 \div \frac{13}{7}$

$x = 52 \times \frac{7}{13}$

$x = 4 \times 7$

$x = 28$

Hence, the number of girls is 28

then the number of boys will be 52-28= 24

Therefore, the number of girls is 28 and the number of boys is 24.
