Question

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

Answer 1

There are 60 quarters.

Explanation:

1. Calculate the number of pennies:

To calculate the number of pennies you should multiply the total number of coins by the proportion of pennies.

`240*(11)/(20)=132`

2. Calculate the number of nickels:

To calculate the number of nickels you should multiply the total number of coins by the proportion of nickels.

`240*(4)/(20)=48`

3. Calculate the number of quarters:

To calculate the number of quarters you should subtract from the total of coins the number of pennies and nickels.

`240-132-48=60`

Therefore there are 60 quarters.
