Simplifying Ratios Worksheet Generator
Create fresh ratio-reduction practice where every pair is built from a coprime base ratio and one whole-number scale factor. The answer key therefore always shows the ratio in lowest terms.

Treat a ratio like a fraction for reduction: divide both terms by the same greatest common factor.
Ask students to check that the simplified terms have no common factor greater than 1 before moving on.
Use the small set for structure first, then move to medium or large numbers after the reduction process is secure.
Mix simplifying, tables, unit rates, proportions, and percent proportions in one generator.
Connect ratios to percents →Practice part / whole = percent / 100 after equivalent ratios are secure.
Frequently asked questions
Are simplified answers always in lowest terms?
Yes. Each problem starts from a coprime base pair and scales both terms by the same factor.
Can I increase the number size?
Yes. Small, medium, and large sets increase both the base terms and possible scale factors.
Can I make another version?
Yes. New problems changes the seed while keeping the selected skill and number range.
Is an answer key available?
Yes. The direct PDF can append a separate answer-key page.
