Question

The cost of five books is 71 dollars what is the cost of each book

Answer 1

Divide 71 and 5 to get a decimal since 71 does not end with 5 or 0. Do it to get 14 1/5 or 14.2

Answer 2

Well, for this you would need to  do  71 divided by 5. Each book would cost $14.20.
To  check this, simply do 5 multiplied by 14.20 and you get 71.
