Unit 8 Contents

Kim solved the problem like this and then checked her division with multiplication:

Mr. Moreno added, “To keep the problem the same, when the decimal point in the divisor is moved to make a whole number, the decimal point in the dividend should be moved the same number of places.”

Use partial quotients to solve the problems. Think of convenient numbers and facts to help you estimate the quotients.

1. 14.8 ÷ 0.2 =
2. 16.4 ÷ 0.2 =

1. 0.72 ÷ 0.09 =
2. 0.738 ÷ 0.09 =
