Frequently asked questions

▸What percentage skills are taught in Grade 7?

Grade 7 extends percentages into full problem solving: finding what percent one number is of another, finding the whole from a part, and applying a percent increase or decrease to a price. Find the Percent targets the "what percent" skill, Find the Whole recovers the whole, and Percent Increase and Decrease handles percent change.

▸How do you find what percent one number is of another?

Divide the part by the whole, then multiply by 100. For 15 out of 60, that is 15 ÷ 60 = 0.25 = 25%. The Find the Percent sheet drills exactly that, with values chosen to give clean percentages. When the part is bigger than the whole the answer passes 100%: 60 out of 40 is 150%.

▸What is the percent proportion?

It is the setup part over whole equals percent over 100. Cross-multiplying solves for whichever quantity is missing, which is why the same method works for every percent question a Grade 7 student meets.

▸Can I mix "percent of a number" and "what percent" on one worksheet?

Each sheet holds a single kind of question so practice stays focused, but generating one of each takes seconds — switch the card, keep the same count, and print both. The answer key prints on its own page for each sheet.

▸Which paper size and font work best?

Choose A4 or US Letter in the controls and both the preview and PDF reflow to match. Medium font suits most students, while the easy-read font helps anyone who finds dense pages hard to track.
