Exact-construction rule: number problems are built from a known rate and compatible whole, while money problems use integer-cent arithmetic. That keeps the intended answer exact instead of hiding a rounding decision in the key.
Teaching note 1

Ask students to estimate the whole before calculating. If 25% is 20, the whole must be larger than 20 and should be near four groups of 20.

Teaching note 2

Keep the rate set narrow when the learning goal is reverse reasoning rather than percent-fact recall.

Teaching note 3

Once the structure is stable, mix this skill with finding-the-percent problems so students must decide which quantity is missing.

Frequently asked questions

Why are the missing-whole answers clean?

The generator chooses the whole first, calculates an exact part, and then hides the whole.

Can I use benchmark percentages only?

Yes. Benchmark mode focuses on 10%, 20%, 25%, 50%, and 75%.

Does custom mode support 1% to 200%?

Yes. Custom mode uses whole-number percentages within that range.

Can the answer key be removed for student copies?

Yes. Turn off Include answer key before downloading the PDF.
