1) If there are 54 people in a class and the ratio of girls to total people is 2:5, how many
girls and boys are there in the class?

Respuesta :

From the ratio you can deduce 2:5 girls and 3:5 boys. Divide 54 by 5 and you get 10.8. 10.8*2 = 21.6 and 10.8*2= 32.4 which adds to the total 54. There cannot be a fraction of a person, you need to round the decimals. There are 22 girls and 32 boys.

There are 22 girls and 32 boys in the class.
