# Multiply Decimal Numbers by One-Digit Numbers

In this worksheet, students practise multiplying a decimal number by a single digit number by 'getting rid of the decimal' first. Key stage:  KS 2

Curriculum topic:   Maths and Numerical Reasoning

Curriculum subtopic:   Decimals

Difficulty level:   ### QUESTION 1 of 10

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

Example:

Work out 3.87 × 7

If you multiply 3.87 by 100, you get 387.

Now work out 387 × 7 = 2709

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

This gives the answer 2709 ÷ 100 = 27.09
