Question

George has a coin collection. 16% of the coins are quarters from the

1990s. If he has 32 quarters from the 1990s, how many total coins does he
have?

Answer 1

200

Explanation:

Given that :

16% of coins are quarters from 1990

Number of quarters from 1990 = 32

Since 16% = 32 quarters

The number of the total coins can be obtained thus :

Let the total number of coins = x

16% = 32

100% = x

Cross multiply :

0.16x = 32 * 1

0.16x = 32

x = 32 / 0.16

x = 200

Hence, total number of coins in the collection = 200
