 # Decimals: Multiplying by 10, 100, 1000

In this worksheet, students multiply whole numbers and those involving decimals by 10, 100 and 1000. Key stage:  KS 2

Curriculum topic:   Number: Multiplication and Division

Curriculum subtopic:   Multiply/Divide Using Decimals

Difficulty level:   ### QUESTION 1 of 10

In this activity, you will multiply whole numbers and those involving decimals by 10, 100 and 1000.

Multiplying by 10 moves all digits one place to the left.

Multiplying by 100 moves all digits two places to the left.

Multiplying by 1000 moves all digits three places to the left and so on.

Remember that when a digit moves from the tenths place to the units place, it hops over the decimal point.

Examples:

24 × 10 = 240
31.2 × 100 = 3120
0.7 × 1000 = 700

(We need zeros to fill in the gaps in the columns.)
