Question

There are 144 people in line. There are twice as many adults as children in line .How many children in line and how many adults are in line?

Answer 1

48 children and 96 adults

let x be the number of children then number of adults = 2x and

x + 2x = 144

3x = 144 ( divide both sides by 3 )

x = $\frac{144}{3}$ = 48

There are 48 children and ( 2 × 48 ) = 96 adults
