Question

Georgiana increased the amount of miles she can run from 5 miles to 9 miles. What is the percent of change in the amount of miles she can run?

Answer 1

To calculate the percentage change you have to calculate the increase first.

Increase= New number - original number

Then divide the increase by the original value and multiply it by 100

$Increase=9-5=4$

Percentage:

$\frac{4}{5}\cdot100=80$

The percent of change of the miles she can run is 80%
