Why build your own ratio and proportion quiz

A printable worksheet is easy to find, but it rarely matches the examples your teacher used this week. A ratio and proportion math quiz built from your own notes covers the unit rates, scale drawings and recipe problems you were actually given.

Scale drawings and map distances
Unit rates and best-buy comparisons
Equivalent ratios and cross-multiplication
Word problems on recipes, mixtures and speed

Example ratio and proportion quiz questions

A recipe uses 2 cups of flour for every 3 eggs. How many cups of flour go with 9 eggs?6 cups. The ratio 2:3 scales by 3, so 3 times 2 gives 6 cups of flour for 9 eggs.

True or false: the ratios 4:6 and 10:15 form a proportion.True. Both simplify to 2:3, so the two ratios are equal.

If 5 pens cost $7.50, what do 8 pens cost?$12.00. The unit rate is $1.50 per pen, and 8 times $1.50 is $12.00.

A map scale is 1 inch to 25 miles. How far apart are two towns that are 3.5 inches apart on the map?87.5 miles. Multiply 3.5 by 25 to convert map inches into real miles.

Solve for x: 3/4 = x/12.x = 9. Cross-multiply to get 3 times 12 = 36, and 36 divided by 4 is 9.

How it works

Upload your notes

Add a PDF, slides, a DOCX file, plain text or a photo of the page.

Choose your question types

Select multiple-choice, true/false or open questions for ratio and proportion.

Take the quiz and read the explanations

Answer each question, check why it is right or wrong, then generate a fresh set for more practice.

Ratio and proportion problems are easy to misread, because one wrong cross-multiplication or a missed unit can flip the answer. Quiz questions with explanations show exactly where the reasoning broke down, which is more useful than a score alone.

DeckOwl reads PDFs, DOCX and PPTX files, plain notes and photos of pages, then writes questions you can retake until the method feels automatic.

Frequently asked questions

How do I tell whether two ratios form a proportion?

Write both ratios as fractions and cross-multiply. If the products match, the ratios form a proportion, so 4:6 and 10:15 work because 4 times 15 equals 6 times 10.

What is the difference between a ratio and a proportion?

A ratio compares two quantities, like 2 to 3. A proportion states that two ratios are equal, like 2:3 = 4:6.

Can I export my ratio and proportion quiz?
