In this worksheet, we will learn how to multiply a decimal number by a single digit number.

Example:

Work out 3.87 × 7

Answer:

If we multiply 3.87 by 100, we get 387.

Now work out 387 × 7 = 2709

Then divide 2709 by 100 to 'cancel out' the fact that we multiplied by 100 earlier. 

This gives the answer 2709 ÷ 100 = 27.09
