In a class 18 children are girls A quarter of the children in the class are boys. Altogether, how many children are in the class?

24

Step-by-step explanation:

let x be the number of children in the class , then

number of boys = x , so

x = x + 18 ( multiply through by 4 to clear the fraction )

4x = x + 72 ( subtract x from both sides )

3x = 72 ( divide both sides by 3 )

x = 24

There are 24 children in the class
