  1. Multiplying Decimals Objective: Review/Learn how to multiply decimals.

  2. When multiplying with decimals, you do not need to worry about lining up the decimal point. Let’s take a look at the steps: Step 1: If problem is written horizontally, rewrite it vertically. Step 2: Multiply the problem as you normally would, ignoring the decimal points for now. Step 3: Count the number of decimal places for each number in the problem. Step 4: • Place the decimal point in your answer using the total number of decimal places from the problem.

  3. Example: 2.18 × 4.5 2.18 × 4.5 2.18 2 decimal places × 4.5 1 decimal place 1,090 + 8,720 9,810 2.18 2 decimal places × 4.5 1 decimal place 1,090 + 8,720 9.810 3 decimal places

  4. Your examples:

  5. Sometimes you will need to add more zeros to your product before adding the decimal point. For example: 3.02 × 0.02 = Steps: 1. First, Multiply as you normally would. 2. Count the number of decimal places for each number in the problem. 3.02 2 decimal places × 0.02 2 decimal places 604 3. Place the decimal point in your answer using the total number of decimal places from the problem in your answer. Add zeros as necessary. 3.02 2 decimal places × 0.02 2 decimal places 0.0604 4 decimal places

  6. Homework: Find the product of each exercise. 10.
