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
and divide your answer by 100.
 

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.
