Question

4 A game is being watched by 60 adults and some

children. If there are 20 more adults than children,
how many children are watching the game?
Lo Children

Answer 1

20 children.

Explanation:

We can solve this using an equation or simple mental math:

The equation: x=children x+20=adults

x + (x+20) = 60

2x + 20 = 60

2x = 40

x = 20

Mental Math: 40 plus 20 is 60 and 40 is 20 more than 20 so there are 40 adults and 20 children.
