Wednesday, Oct 16 Lesson 3.8 Divide Decimals by Decimals
Objective: To understand how to estimate and divide decimals by decimals.
Divide Decimals by Decimals When dividing a decimal by a decimal, change the divisor to a whole number. To do this, move the decimal in both the divisor and dividend to the right. Then divide as before.
