Multiply Decimals
Multiplication of decimals is very similar to that of whole numbers. The only
difference here is that we need to count decimal places; otherwise it's exactly
the same as multiplying whole numbers.
To multiply decimals:
- In the numbers being multiplied, count the number of places to the right
of the decimal points.
- Ignoring any decimal points, multiply the numbers.
- Place a decimal point in the product so that it has the same number of
places to the right of it as the total number of places found in step
1.
Examples
| .3 |
(1 decimal place) |
| *.05 |
(2 decimal places) |
| .015 |
(3 decimal places total) |
|
| 4.01 |
(2 places) |
| *10 |
(0 places) |
| 40.10 |
(2 places total) |
|
40.10 can be written more simply as 40.1
