Pre-Algebra builds percent of change on finding a percent of a number. Work out how much the value changed, divide by the starting value, and write the result as a percent with the word increase or decrease. The other kind of question goes forward from a number and a percent.
Also taught in Algebra 1, at its own level and with its own examples.
Select your difficulty
Pick more than one for a sheet that mixes them.
The preview can look cramped on a phone. The PDF and printed sheet come out normal.
Dividing by the new value instead of the original. 10 ÷ 50 gives 20%, which is the size of the change going from 50 back down to 40, not from 40 up to 50.
Also called percent increase, percent decrease or percentage change.
What you can put on this worksheet
Find the percent of change between two values
Find the percent of change from 100 to 75→ 25% decrease
Increase or decrease a number by a percent
120 decreased by 25%→ 90
Rounded to the nearest tenth of a percent
By what percent does 18 increase or decrease when it becomes 75? Round to the nearest tenth of a percent.→ 316.7% increase
Questions about these worksheets
Yes. Every percent of change sheet is free to print and free to download as a PDF. There is no account to make, no email to hand over and no limit on how many you take.
Yes. The answer key prints on a second page, and you can choose whether it shows each question beside its answer or just the answers in a list.
Yes. Print straight from the page, or download the PDF and print that. The sheet is laid out for paper rather than squeezed off a screen, so there is room to work under each question, and the answer key comes out on its own page.
Pre-Algebra is usually taken around 7th or 8th grade, though schools vary and plenty of students meet it earlier or later. Pick the difficulty rather than the grade: the easy level suits a first lesson on it, the hard level suits review before a test.
Yes, as many as you like. The questions are built fresh each time rather than picked from a fixed set of files, so pressing Generate gives a new sheet. That is what you want for a second class, a retake, or two students sitting next to each other.
That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the percent of change questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.
Yes. There are three levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.
You pick from 3: find the percent of change between two values, increase or decrease a number by a percent and rounded to the nearest tenth of a percent. Tick as many as you want and set how many of each, or let it spread them evenly.
Taking the percent of the wrong number, or thinking a 20% rise then a 20% fall returns you to the start. It does not: the fall is 20% of a bigger number, so you end up lower than you began.
