Difficulty level:   ### QUESTION 1 of 10

In this worksheet, you must multiply decimal numbers by a whole number.

Example:

Here are two methods for working out 4 lots of 1.64.

Find four lots of 1.64.
Here we add 1.64 four times.
1.64
1.64
1.64
1.64

Here we multiply 1.64 by 4.

Remember, multiply 164 by 4

 164 4 x 400 4 x 100 240 4 x 60 16 4 x 4 656

Answer: 656 ÷ 100 = 6.56.

Your two answers should be the same, but it is quicker to multiply when using larger numbers.
