 # Multiplication of Decimal Numbers by Single Digit Numbers

In this worksheet, students must multiply one-digit numbers with up to two decimal places by whole numbers. 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 1

Work out:

3.8 × 7

If you multiply 3.8 by 10, you get 38.

38 is a whole number, which is good.

Now work out 38 × 7 = 266.

Then divide 266 by 10 to 'cancel out' the fact that you multiplied by 10 earlier.

This gives the answer 266 ÷ 10 = 26.6.

Example 2

Work out:

3.87 × 7

If you multiply 3.87 by 100, you get 387.

387 is a whole number, which is good.

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.
