How to Solve Proportion and Ratio Word Problems in Class 6 Maths
FAQs on Practice Worksheet on Proportion and Whole Numbers for Class 6 Maths
1. What is proportion in math class 6?
In Class 6 maths, a proportion is a statement that declares two ratios are equal or equivalent. If four numbers, say a, b, c, and d, are in proportion, it is written as a:b :: c:d, which means the ratio a:b is equal to the ratio c:d.
- This is also expressed as the equality of two fractions: a/b = c/d.
- A key rule is that the product of the extremes (a × d) is equal to the product of the means (b × c).
- Understanding proportion helps in solving problems involving equivalent ratios.
2. What are whole numbers for class 6?
Whole numbers for Class 6 are the set of positive integers including zero. They are the basic counting numbers and do not include any fractions, decimals, or negative numbers.
- The set of whole numbers starts from 0 (zero).
- Examples of whole numbers are: 0, 1, 2, 3, 10, 55, 100, and so on.
- These numbers are fundamental for learning other mathematical operations and concepts in the NCERT syllabus.
3. How do you solve proportions with cross multiplication?
To solve proportions using cross multiplication, you multiply the numerator of each ratio by the denominator of the other ratio and set the products equal. This method is used to find an unknown value in a proportional relationship.
For a proportion like a/b = c/x:
- Multiply diagonally: Multiply 'a' with 'x' and 'b' with 'c'.
- Set the products equal: This gives you the equation a × x = b × c.
- Solve for the variable: Isolate 'x' by dividing both sides by 'a' (x = (b × c) / a).
4. How do you check if four numbers are in proportion, for example, 15, 45, 40, and 120?
To check if four numbers are in proportion, you must verify if the product of the first and fourth terms (extremes) is equal to the product of the second and third terms (means). For the numbers 15, 45, 40, and 120:
- The extremes are 15 and 120.
- The means are 45 and 40.
- Product of Extremes: 15 × 120 = 1800.
- Product of Means: 45 × 40 = 1800.
Since the products are equal (1800 = 1800), the numbers 15, 45, 40, and 120 are in proportion.
5. What is the main difference between ratio and proportion for Class 6 students?
The main difference is that a ratio compares two quantities, while a proportion states that two ratios are equal. Understanding this is key for solving ratio and proportion questions for Class 6.
- A Ratio is a comparison. For example, if there are 3 apples and 5 oranges, the ratio of apples to oranges is 3:5.
- A Proportion is an equation showing equality between two ratios. For example, 1:2 = 2:4 is a proportion because both ratios represent the same relationship.
