What is ratio and proportion in maths for Class 6?
If two ratios are equal we say that they are in proportion and use the symbol to equate the two ratios. and say that 2, 4, 60 and 120 are in proportion. We say that 2, 5, 60 and 15 are not in proportion. So, if two ratios are not equal, then we say that they are not in proportion.
What is a proportion in 6th grade math?
A proportion is an equality of two ratios. The ratios in a proportion are equivalent ratios. Two ratios are equivalent if you can multiply or divide both numbers in one ratio by the same value to get the other ratio.
What are ratios and proportions?
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)
How do you find ratios and proportions?
A ratio can be written in different forms like x : y or x/y and is commonly read as, x is to y. On the other hand, proportion is an equation that says that two ratios are equivalent. A proportion is written as x : y : : z : w, and is read as x is to y as z is to w. Here, x/y = z/w where w & y are not equal to 0.
How do you teach ratios and proportions?
To introduce proportions to students, give them tables of equivalent rates to fill in, such as the one below. This will help them learn proportional reasoning. Work with these tables (first using easy numbers) until the students get used to them. You can tie in some of them with real-life situations.
How do you simplify ratios and proportions?
How to Simplify a Ratio A : B when A and B are both whole numbers
- List the factors of A.
- List the factors of B.
- Find the greatest common factor of A and B, GCF(A, B)
- Divide A and B each by the GCF.
- Use the whole number results to rewrite the ratio in simplest form.
How do you do ratios in maths?
To calculate a ratio of a number, follow these 3 steps:
- Add the parts of the ratio to find the total number of parts.
- Find the value of each part of the ratio by dividing the number by the total number of parts calculated in step 1.
- Multiply each part of the original ratio by the value of each part calculated in step 2.

How do you solve proportions?
Solving proportions Solving a proportion means to find an unknown quantity within a proportion. We can do so using cross-multiplication. As an example, let’s solve the proportion, In order for this proportion to be true, we must have . So, Solving this equation by dividing both sides by 91, we find that .
