Question

Eric has 240 coins in his collection.11/20 of the coins are pennies.4/20 of the coins are nickels.the rest of the coins are quarters.how many of you the coins are quarters?

Answer 1

Explanation:

240/20 = 12

Denominator = 240

11/20 = both numerator and denominator multiplied by 12 = 121/240

4/20 = both sides multiplied by 20 = 80/240

121 + 80 = 201

240 - 201 = 39 quarters in collection
