Free Printable Percentages Greater Than 100 Worksheets for Class 8

In 8th grade, practice with percentages over 100% serves to solidify proportional reasoning and prepare students for pre-algebra. The problems may involve more complex numbers or require students to set up and solve equations where the percentage or the original amount is the unknown variable.

Frame percentage increase problems as algebraic equations. For example, ask students to solve for an unknown: "After a 150% increase, the new population is 500. What was the original population?" This requires students to set up and solve an equation like 2.5x = 500, strengthening their algebraic thinking.

Challenge students with problems where they must find the original amount or the percent change. For example: "A stock's value grew to $70, which is 140% of its original price. What was the original price?" You can also introduce problems with multiple consecutive percentage changes to build advanced reasoning.

Even in 8th grade, students can still confuse the "increase" with the "final amount." In a problem about a 120% increase, they might multiply by 1.2 instead of 2.2. Reinforcing that the final amount is the original 100% plus the increase helps correct this algebraic setup error.

You can assign this worksheet digitally on the Wayground platform for automated grading or download the printable PDF for offline classwork. Every worksheet includes a complete answer key. The PDF format is also a great way to provide rigorous practice while reducing student screen time.

For students who need it, you can enable the Read Aloud feature for digital assignments or increase the font size and spacing on the printable version. To challenge advanced learners, ask them to create their own word problems involving percentages greater than 100, which requires them to think about the structure of the problem itself.
