Pe un teren de sport, fetele reprezinta un sfert din numarul baietilor. Daca pleaca 8 baieti si vin acelasi numar de fete, raportul va fi de 1 la 2.Cate fete si cati baieti sunt?

the girls be 12 and boys be 48 respectively

Step-by-step explanation:

The computation of the number of boys and number of girls is shown below:

Let us assume A be girls

And, b  be boys

According to the question

b = 4 × a

b - 8 = 2 × (a + 8)

b - 8 = 2 × a + 16

4 × a -8 = 2 × a + 16

4 × a  - 2 × a = 16 + 8

2 × a = 24

a = 12

Now

b = 4 × a

= 4 × 12

= 48

Hence, the girls be 12 and boys be 48 respectively
