Question

Lily  estimated a quotient of 120 and found an actual of 83 .what should she do next? Explain .

Answer 1

Since her estimated quotient is way off from the actual quotient, we can find the percent error.  The formula for this is

 

Percent error = | (estimated quotient - actual quotient) / (actual quotient) | * 100

 

 

The vertical lines represent absolute value.
