During a recent election, 42 of every 100 registered voters in a certain city voted. If there were 158 , 200 registered voters in that city, how many people voted?
Seeing as there are 1582 sets of 100 people (158200 ÷ 100) multiplying 42 by 1582 should get you the answer. 1582 × 42 = 66444. 66444 people voted in that city.
