How to Solve Ratio and Proportion Problems in Class 6 Maths
FAQs on Proportion Worksheet for Class 6 Maths (With Answers)
1. What is proportion in Class 6 Maths?
In Class 6 Maths, a proportion is a statement that says two ratios are equal or equivalent. If four numbers, say a, b, c, and d, are in proportion, it means the ratio of the first two (a:b) is equal to the ratio of the last two (c:d), written as a:b :: c:d.
- It is a way of comparing ratios to see if they represent the same relationship.
- The rule to check for proportion is: Product of extremes = Product of means.
- For example, in a:b :: c:d, 'a' and 'd' are extremes, while 'b' and 'c' are means. So, a × d = b × c.
2. Are 15, 45, 40, and 120 in proportion?
Yes, the numbers 15, 45, 40, and 120 are in proportion. To check this, we see if the product of the extreme terms equals the product of the middle terms (means).
- The four numbers can be written as the proportion 15 : 45 :: 40 : 120.
- Extreme terms are 15 and 120. Their product is 15 × 120 = 1800.
- Middle terms (means) are 45 and 40. Their product is 45 × 40 = 1800.
- Since the product of extremes (1800) is equal to the product of means (1800), the numbers are in proportion.
3. What is the formula for ratio for Class 6?
In Class 6, a ratio is a formula used to compare two quantities of the same unit, and it does not have a single formula but is expressed as a relationship. It is represented by the symbol ':' or as a fraction.
- If we have two quantities 'a' and 'b', the ratio of 'a' to 'b' is written as a : b or a/b.
- 'a' is called the antecedent (first term), and 'b' is the consequent (second term).
- For a ratio to be meaningful, both quantities must be in the same units. For example, the ratio of 2 kg to 500 g is found by converting 2 kg to 2000 g, making the ratio 2000:500 or 4:1.
4. How do you solve proportion problems?
You can solve proportion problems, especially those with a missing term, by using the rule of proportionality or cross-multiplication. The fundamental rule states that the product of the extremes is equal to the product of the means.
For example, to find the missing term in 5 : 10 :: 20 : x:
- Step 1: Identify the extremes (5 and x) and the means (10 and 20).
- Step 2: Set their products equal: 5 × x = 10 × 20.
- Step 3: Solve for the unknown: 5x = 200.
- Step 4: Calculate the final value: x = 200 / 5, so x = 40.

7. Are 30, 40, 50, and 60 in proportion?
No, the numbers 30, 40, 50, and 60 are not in proportion. We can verify this by checking if the product of the extremes equals the product of the means.
- The proportion would be set up as 30 : 40 :: 50 : 60.
- Product of extremes: 30 × 60 = 1800.
- Product of means: 40 × 50 = 2000.
- Since 1800 is not equal to 2000, the ratios 30:40 and 50:60 are not equivalent, and the numbers are not in proportion.
8. What types of proportion questions are in this Class 6 worksheet?
This proportion questions for Class 6 worksheet includes a variety of problem types to ensure a thorough understanding of the topic. The exercises are designed to test different aspects of proportional reasoning.
- Identifying Proportions: Determining if a set of four numbers forms a proportion.
- Finding Missing Terms: Solving for an unknown value in a proportional statement (e.g., 2 : 4 :: x : 8).
- Equivalent Ratios: Matching or creating ratios that are equal.
- Word Problems: Applying the concept of proportion to real-life scenarios like recipes, maps, and mixing quantities.
9. What is the difference between ratio and proportion?
The main difference is that a ratio is a comparison of two quantities, while a proportion is an equation stating that two ratios are equal. A proportion is essentially a relationship between two equivalent ratios.
- Ratio Example: The ratio of 3 apples to 4 oranges is 3:4. It's a single comparison.
- Proportion Example: The statement that the ratio 3:4 is equal to the ratio 6:8 is a proportion, written as 3:4 :: 6:8.
- Essentially, a proportion shows that two different pairs of numbers have the same relative size.
