Algebra 1 writes each percent problem as an equation, part = percent × whole, and solves for the missing piece. The hard questions use percents under 1%, percent increase and decrease, answers rounded to a tenth of a percent, and percent error, where the difference is compared with the true value.
Also taught in Pre-Algebra, at its own level and with its own examples.

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.
A student estimates 120 people at a game. The actual count is 150. Find the percent error.
The difference is 150 - 120 = 30.
Compare it with the true value: 30 ÷ 150 = 0.2.
The answer is 20%.
Where students go wrong
Writing a small percent as the wrong decimal. 0.05% is 0.0005, not 0.05, so move the decimal two places left even when the percent is already less than 1.
Also called what percent is, finding the whole from a percent or percent proportion.
What you can put on this worksheet
The three percent questions
What is 25%of 80?→ 20
Word problems

Percent error

Questions about these worksheets
Yes. Every percent problems 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.
Algebra 1 is usually taken around 8th or 9th 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 problems 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 two 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 5: the three percent questions, word problems, percents under 1%, over 100%, and answers to round and percent error. Tick as many as you want and set how many of each, or let it spread them evenly.
Dividing the wrong way round. The part goes on top and the whole underneath; doing it the other way gives 4, or 400 percent, which should look wrong straight away.
