1. 6.2.5 Multiplying Decimals 6.2.6 Dividing Decimals

2. Multiplying Decimals by Whole Numbers
Step #1: Multiply as you would with whole numbers Step #2: Count the number of places to the RIGHT of the decimal point Step #3: Insert the decimal point into the answer so the SAME number of places are to the RIGHT of the decimal point

3. Multiplying by Powers of 10
Simply move the decimal point to the RIGHT the SAME number of ZEROS as there are in the power of 10

4. Your Turn!
8.32 x 9
7.10 x 10
.016 x 3

5. Multiplying Decimals
Step #1: Multiply as you would with whole numbers Step #2: Count the number of places to the RIGHT of EACH decimal point Step #3: Insert the decimal point into the answer the TOTAL number of places that are to the RIGHT of each decimal point

6. Your Turn!
8.1 x 5.6
6.32 x .09
1.785 x .2
BONUS: x 1.9

7. Dividing Decimals by Whole Numbers
Step #1: Place the decimal point in the quotient DIRECTLY ABOVE the decimal point in the dividend Step #2: Divide as you would whole numbers

8. Dividing Decimals by Decimals
Step #1: Move the decimal point of the divisor (the number outside the box) to the RIGHT the number of spaces needed to make it a whole number Step #2: Move the decimal point of the dividend (the number inside the box) to the RIGHT the SAME number of spaces as the divisor Step #3: Divide as normal

9. Your Turn!
TIP: Say the problem out loud. The number that follows the phrase “divided by…” is the number that goes OUTSIDE the box.
9.6 ÷ 1.2
÷ 2.3
57.8 ÷ 3.4
