Ratio Practice
An endless supply of never-repeating ratio problems with instant feedback. Simplify ratios, find unit rates and unit prices, scale recipes, and compare deals — one problem at a time.
1 Practice
Type your answer and press Check answer (or Enter). A wrong answer earns a hint first; a second miss walks you through the full solution.
How to enter answers
- Ratio: use a colon, like
2:3. When a problem says “simplest form”,4:6will not count — reduce it. - Numbers: an integer (
50), a fraction (2/3), or a decimal (0.5). - Money: dollars and cents like
1.50(no dollar sign needed). - Choice: the letter
AorB.
2 What you’ll practice
Every problem is generated fresh from 12 templates across four question types — a problem never repeats until its whole pool is used up.
Simplify ratios
Divide both sides by their greatest common factor. Watch the order when the question names “girls to boys”.
Unit rates and prices
“Per” means divide. Find miles per hour, dollars per pound, and pick the better buy by comparing unit prices.
Equivalent ratios and scaling
Multiply both sides by the same number to scale a ratio up — for recipes, missing terms, and splitting totals.
3 Watch out for these
The three mistakes students make most often on ratio problems.
Wrong: 9 boys, 12 girls → 9:12. Right: girls to boys = 12:9 = 4:3. The first word named goes first.
Wrong: 2:3 → 4:5. Right: 2:3 → 4:6. Ratios grow by multiplication only.
Wrong: 150 miles in 3 hours → 3 ÷ 150. Right: 150 ÷ 3 = 50 mph. The word after “per” is the divisor.
