Question

How can emily use the above to make an estimate for 576 ÷8

Answer 1

Given the equation :

$576\div8​$

We will use estimation to find the value of the given expression

So, the best estimation for the number 576 is = 600

The best estimation for the number 8 is = 10

So, the given expression is approximately = 600 ÷ 10 = 60

===================================================================

We can calculate the error of the approximation as following :

The actual value is : 576 ÷ 8 = 72

So, the difference is = 72 - 60 = 12

so, the percentage of error will be :

$\frac{12}{72}\cdot100=16.7\%$
