Question

Before the clowns arrived, only 35% of the children wore happy faces. If 117 children did not wear happy faces, how many children were there in all?

Answer 1

180

Explanation:

If 35% did not wear happy faces, then 100% -35% = 65% did wear happy faces.

Then we have ...

... 117 = 65% × (all children)

... 117/0.65 = all children = 180 . . . . . . divide by 65% = 65/100 = 0.65

There were 180 children in all.
