Answer:
52
Step-by-step explanation:
Lets put the ratio like this: 6x (boys) : 7x (girls)
because we know that the amount of girls is 28 we can set them equal as so:
7x = 28
÷ divide both sides by 7
x = 4
now add 6x + 7x to get the total people = 13x and because x equals 4, we can multiply 13 by 4. Which is 52
