This activity is about decimal multiplication.
Example
Do the following multiplication.
| 6.74 × 61 | = |
Answer
We multiply 6.74 by 100, so that we are now dealing with whole numbers.
We carry out a long multiplication of 674 x 61 to get 41,114.
Finally, we divide this by 100, to reverse that first step.
This gives us the answer 411.14
Alternatively, we can remove the decimal point, do the calculation, and then add the decimal point back in. Make sure that you have the same number of decimal places in your answer as in the original calculation. In this case, that is two decimal places, giving us 411.14
