Question

Ava read 66 books in 12 months. how many books per month did she read?

Answer 1

she read 5.5 books per month x

Answer 2

Divide 66 with 12

66/12 = 5.5

Ava reads 5.5, or 5 whole books per month. (Note that you never round up, because you are looking for the total amount, and she did not read the other 1/2 of the last book).

hope this helps
