How to use the ratio practice
- Pick a skill. If you are not sure, start with Write a ratio and move along the row as each one gets easy.
- Answer each question. Ratios have one box for each part. On a phone, a number pad appears below the question.
- Read the hint when an answer is wrong. It shows the method: scaling both parts, finding one equal part, or dividing for a unit rate.
- Check the stars. 8 or more out of 10 means the skill is secure. The results list the questions to practice again.
How answers are marked
When a question asks you to write a ratio, any equivalent ratio is marked right. For example, 6 : 4 and 3 : 2 both count for 6 blue and 4 orange. The hint still shows the simplest form.
Simplify questions need the simplest form, because that is the skill being practiced. Rates and prices are marked by value, so 2.5 and 2.50 both count.
A sensible order for ratio practice
Ratios rest on multiplication and division facts. A child who knows the times tables well can scale a ratio table quickly. This order follows the US Common Core and the NCERT books:
- Ratio language (grade 6): “for every”, part-to-part and part-to-whole ratios.
- Equivalent ratios (grade 6): ratio tables, double number lines and simplest form. The ratio calculator shows the steps.
- Tape diagrams (grade 6): sharing an amount in a given ratio.
- Rates and unit rates (grade 6): speed, unit price and the best buy. Check them with the unit rate calculator.
- Proportions (grade 7): proportional relationships, the constant k and scale drawings.
When a ratio skill won’t stick
- Swapping the order: writing 3 : 2 for “2 cups of flour to 3 cups of milk”. Say the words with the numbers: flour to milk, 2 to 3.
- Adding instead of multiplying: thinking 2 : 3 is the same as 4 : 5. Equivalent ratios multiply both parts by the same number: 4 : 6.
- Mixing up part and whole: 12 girls and 18 boys means girls are 12 out of 30, not 12 out of 18.
- Dividing the wrong way for a unit rate: say the unit you want. Dollars per ounce means dollars ÷ ounces.
A 10-minute routine
- Minutes 1–2: scale a ratio out loud. For example, 2 : 3 is 4 : 6, 6 : 9 and 20 : 30.
- Minutes 3–8: one round of 10 questions on the current skill.
- Minutes 9–10: read the hints for anything missed and try one again on paper.
For parents and teachers in the classroom
- Share a skill: add ?skill=write, equiv, simp, table, tape, compare, unit, price, speed, prop, propr, scale or word to the address.
- Projector friendly: large numbers, clear pictures and an on-screen number pad work well for a whole-class warm-up.
- Private by design: no account and nothing stored online.

Questions parents ask
How can my child practice ratios online for free?
Use the practice tool at the top of this page. Pick a skill, such as equivalent ratios or unit rates, and answer 10 questions one at a time. Every answer is marked straight away, with a hint when it is wrong.
How do I type a ratio answer?
Each part of the ratio has its own box. For 2 : 3, type 2 in the first box and 3 in the second. When the question asks for any ratio, an equivalent one like 4 : 6 is marked right too.
Which ratio skill should my child start with?
Start with Write a ratio, then Equivalent ratios and Simplify. Ratio tables, tape diagrams and unit rates come next. Proportions, proportional relationships and scale drawings come last.
What grade are these ratio questions for?
Grades 6 and 7 (classes 6 to 8 in India). Ratios, tables, tape diagrams and unit rates suit grade 6. Proportions, proportional relationships and scale drawings suit grade 7.
Can teachers use this ratio practice in class?
Yes. Link to a skill with ?skill= at the end of the address, for example /ratios/practice/?skill=unit. Every child gets their own random questions, and nothing needs a login.
Do the questions repeat?
No. Every round makes new random questions, so the same skill can be practiced again and again.
