Practical ratio examples are everywhere once you start looking: pocket money split between two children, a recipe doubled for guests, and boys and girls counted in a class. A ratio simply compares two quantities, and Grade 6 is where that comparison turns into a tool your child can use daily.
I have taught Grade 6 math for over thirty years, and ratios click fastest through real stories, not bare numbers. Below are the examples I use in class, in the same order I teach them, with a free worksheet at the end for practice.
What Is a Practical Ratio?
A practical ratio compares two real quantities of the same kind and writes the comparison in lowest terms. If a class has 10 boys and 15 girls, the ratio of boys to girls is 10:15, which simplifies to 2:3. The numbers stay honest, only smaller and easier to read.
Think of a ratio as a recipe card. It does not tell you how many spoonfuls are in the bowl. It tells you how the spoonfuls relate to each other. That is why 2:3 can describe a class of 25 children or a class of 50 children, as long as the balance stays the same.
One habit matters more than any other: always write the numbers in the order the question asks. Boys to girls is not the same as girls to boys, and swapping them is the most common slip I mark.
How Do Ratios Work With Money?
Ratios split money fairly when the split is not equal. If two friends earn Rs. 900 in the ratio 2:1, the total parts are 3, each part is worth Rs. 300, so one friend gets Rs. 600 and the other gets Rs. 300. Add the shares back and you get Rs. 900, which checks the answer.
Here is a second money example I use with parents. A mother gives her two children pocket money in the ratio 3:2 and the total is Rs. 500. The parts add to 5, so each part is Rs. 100. The first child gets Rs. 300 and the second gets Rs. 200. I ask children to check their answer the same way every time: add the shares and match the total.
If your child wants paper practice with money, recipes and class data together, try my free Practical Ratio Worksheet for Grade 6. It uses the same style of stories, so the questions will feel familiar.
How Do Ratios Work in Recipes?
Ratios scale a recipe up or down without changing its taste. If a pancake recipe uses flour and milk in the ratio 2:1, doubling the recipe means 4 parts flour to 2 parts milk, and halving it means 1 part flour to half a part milk. The ratio stays 2:1, only the amounts move.
Say a recipe for 4 children uses 6 cups of flour and 3 cups of sugar, a ratio of 2:1. For 8 children, double both: 12 cups of flour and 6 cups of sugar. For 2 children, halve both: 3 cups of flour and 1.5 cups of sugar. The taste stays the same because the balance never changes.
I love recipe ratios because children can test them in the kitchen. When a child doubles a recipe herself and it works, she never forgets what a ratio does.
How Do Ratios Work With Class Data?
Ratios turn a class list into one clear comparison. If a class has 12 boys and 18 girls, the ratio of boys to girls is 12:18, which simplifies to 2:3, and the ratio of girls to the whole class is 18:30, which simplifies to 3:5. One table, two useful facts, no guessing.
Reading a table is a skill of its own. I teach children to point at the two columns the question names, write those two numbers down, and only then simplify. The children who skip the pointing step are the ones who mix up rows.
This is exactly the kind of reasoning Common Core standard 6.RP.A.3 asks Grade 6 students to build: using ratio reasoning to solve real problems with tables and stories, not just bare sums.
How Do You Share an Amount in a Given Ratio?
Sharing in a given ratio takes three steps: add the parts, divide the total by the parts to find one part, then multiply to find each share. To share Rs. 800 in the ratio 3:1, add 3 + 1 to get 4 parts, divide 800 by 4 to get Rs. 200 per part, then give Rs. 600 and Rs. 200. The shares add back to Rs. 800.
Work it slowly the first few times. Step one, parts. Step two, one part. Step three, shares. I write those three words on the board for a full week when I teach this, and I have watched the routine rescue many test papers.
Try one with your child tonight: share 40 stickers in the ratio 3:2. The parts are 5, one part is 8 stickers, so the shares are 24 and 16. Then ask her to add them back. That check is the habit that keeps marks safe.
Mistakes I See Every Year
Mistake one: a child writes the ratio backwards, giving girls to boys when the question asks boys to girls. Fix it by underlining the order in the question first.
Mistake two: a child forgets to simplify, leaving 12:18 instead of 2:3. Fix it by dividing both numbers by their common factor before writing the answer.
Mistake three: a child adds the numbers instead of comparing them, answering 30 when the question asks for a ratio. Fix it by asking: does the question want a comparison or a total?
One more slip: sharing money without adding the parts first. A child who divides by 3 instead of 4 when the ratio is 3:1 will never match the total, and the total check catches it every time.
Try It Yourself: 3 Quick Questions
Cover the answers, let your child try, then check together.
- A fruit bowl has 8 apples and 12 oranges. What is the ratio of apples to oranges in simplest form? Answer: 2:3. Divide both numbers by 4.
- Share Rs. 700 in the ratio 4:3. How much does each person get? Answer: Rs. 400 and Rs. 300. The parts add to 7, one part is Rs. 100.
- A recipe uses rice and water in the ratio 1:2. How much water goes with 3 cups of rice? Answer: 6 cups. Double the rice, double the water.
Key Takeaways
- A ratio compares two quantities of the same kind, written in lowest terms.
- Money splits, recipes and class tables all run on the same three steps: parts, one part, shares.
- Always write the numbers in the order the question asks.
- Simplify before you answer, and check shares by adding them back to the total.
- Real stories make ratios stick far better than bare numbers.
If your child handled those three questions, she is ready for a full page of practice. Print the free Practical Ratio Worksheet for Grade 6 and sit with her for the first two questions only. You will be surprised how quickly she takes over.

Frequently Asked Questions
What is a ratio in simple words?
A ratio compares two quantities of the same kind. If a class has 10 boys and 15 girls, the ratio of boys to girls is 10:15, which simplifies to 2:3. It tells you how the two numbers relate, not how many there are in total.
How do you simplify a ratio?
Divide both numbers by their greatest common factor. For 12:18, divide both by 6 to get 2:3. Keep dividing until the two numbers share no common factor except 1.
What is the difference between a ratio and a fraction?
A ratio compares two quantities, while a fraction names a part of a whole. The ratio 2:3 compares boys to girls, but the fraction of boys in the class is 2 out of 5. Same numbers, different jobs.
Can a ratio be written as 2 to 3?
Yes. The ratio 2:3 can also be written as “2 to 3”. Both forms mean the same comparison. In Grade 6 work, the colon form is the one children meet most often.
When do we use ratios in daily life?
We use ratios when we share money, scale recipes, read class data, mix paint and compare prices. Any time two quantities need to stay in balance while the amounts change, a ratio is doing the work.
