To calculate 0.81 × 0.4, you multiply the two numbers together:
0.81 × 0.4 = 0.324
To calculate the product of 0.81 and 0.4, you would multiply the two numbers together. Here's how you can do it:
Step 1: Write down the numbers you want to multiply: 0.81 and 0.4.
Step 2: Multiply the decimal numbers as you would with whole numbers. Start with the rightmost digit (0.1 place) and move to the left.
- First, multiply 0.1 by 1 (the digit in the same place) to get 0.1.
- Next, multiply 0.01 (0.1 place multiplied by 0.1 place) by 8 (the digit in the same place) to get 0.08.
- Then, multiply 0.001 (0.01 place multiplied by 0.1 place) by 4 (the digit in the same place) to get 0.004.
Step 3: Add up the products from Step 2.
- 0.1 + 0.08 + 0.004 = 0.184.
Therefore, the product of 0.81 and 0.4 is 0.184.
