To multiply decimals, you can follow these steps:
Ignore the decimal points: Multiply the numbers as if they were whole numbers.
Count the decimal places: Count the total number of digits after the decimal point in both numbers.
Place the decimal point: Put the decimal point in the product so that it has the same number of digits after the decimal point as the original numbers.
For example, to multiply 0.7 and 0.08, you can:
Ignore the decimal points and multiply 7 and 8 as if they were whole numbers.
The product is 56/1000, or “fifty six thousandths”.
As a decimal, this is written 0.056.
You can also check your answer by thinking about what it means to multiply by 0.5 (or one half).
To multiply decimals, we multiply them just like whole numbers. We count the number of digits behind the decimal in both numbers we're multiplying, and make sure our answer has the same number of digits after the decimal. - We can check our answer by thinking about what it means to multiply by 0.5 (or one half).
