How many students in the class have either glasses or contacts? We often get reports about how much something has increased or decreased as a percent of change. The percent of change tells us how much something has changed in comparison to the original number. There are two different methods that we can use to find the percent of change.

The Mathplanet school has problem solving in percentage its student body from students to from last year. How big is the increase in percent? We begin by subtracting the smaller number the old value from the greater number the new value to find the amount of change.

Then we find out how many percent this change corresponds to when compared to the original number of students. Since we have a percent of change that is bigger than 1 we know that we have an increase. To find out how big of an increase we've got we subtract 1 from 1. How much will the skirt cost after the discount? To solve problems with percent we use the percent problem solving in percentage shown in "Proportions and percent". Example The Mathplanet school has increased its student body from students to from last year, problem solving in percentage.
