Question from Gary, a parent:

How do I estimate the quotient. and then tell what compatible numbers were used. 703/7

Hi Gary,

The technique of estimation using compatible numbers is to identify numbers which are close to the numbers in your problem that make the calculation easy. For example 163/8 is approximately 160/8 and here the arithmetic is easy since 16/8 = 2. thus 163/8 is approximately 160/8 = 20.
