1. Multiply 2. Move the decimal Multiplying Decimals 1. Multiply 2. Move the decimal
Multiply Decimals Step 1 --- Ignore the decimal Step 2 --- Rewrite the problem Step 3 --- Multiply the problem Step 4 --- Underline all numbers to the right of decimal(s) in original problem Step 5 --- Move decimal that many places left in your answer
Steps 1 & 2 Ignore decimals and rewrite the problem 4 . 5 6 X 0 . 3 9 4 5 6 x 3 9
Step 3 Multiply problem without decimals 4 5 6 x 3 9 4 1 0 4 + 1 3 6 8 0 1 7 7 8 4
Step 4 x 0. 3 9 --------------- Underline numbers to the right of decimals in original problem 4. 5 6 x 0. 3 9 --------------- ( 4 places)
Step 5 Move decimal that many places left in answer 4 5 6 x 3 9 4 1 0 4 + 1 3 6 8 0 1 7 7 8 4 ( 4 places)
