Answer 2

There are 70 girls in school.

Step-by-step explanation:

Let the number of boys be x

We are given that The number of girls is 14 2/7% of the number of boys

No. of girls = $14\frac{2}{7}\%x=\frac{100}{700}x$

We are given that School has 560 students.

So,$x+\frac{100}{700}x=560$

$\frac{800}{700}x=560$

$x=\frac{560 \times 700}{800}=490$

No, of girls = Total No. of students - No. of boys = 560-490=70

Hence There are 70 girls in school.
