Apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.
Solution:
Need to determine what operation is required to get one-tenth of a number and 10 times of a number
To get one tenth of a number, divide the number by 10.
For example to get one – tenth of 100, divide it by 10, we get 10 as a result.
[tex]\frac{1}{10} \times 100 = 10[/tex]
To get ten times of a number, multiply the number by 10
For example 10 times of 10 = 10 x 10 = 100
Hence apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.
