In this activity, we will multiply by numbers less than 1.

**Method**

The easiest way to multiply using decimals is to **count how many decimal places** you have in your calculation and make sure that you have the **same number **in your answer.

For example, if you wanted to multiply 27 x 0.__07__ we have **two decimal places** - we've underlined them so you can see them easily!

Having counted them, we **remove the decimal point **and simply multiply the digits together: 27 x 7 = 189

Finally, we put the decimal point back in, making sure we still have **two** decimal places: **1. 89**

Pretty simple, right?

Here's one more example for you to look at:

42.65 x 0.006

First, count how many decimal places we have in 42.__63__ x 0.__006__ - we've underlined them again so you can spot them easily! There are** five **decimal places.

Remove the decimal point and do this calculation: 4263 x 6 = 25578

Finally, add the decimal point back in, making sure we have **five **decimal places: **0. 25578**

Let's have a go at some questions now
