### Exercise 8.2

People encounter several circumstances, amounts, activities, etc. in daily life. It is frequently needed to measure and compare these amounts. Humans, in fact, occasionally evaluate themselves against others in terms of their size, height, grades, speed, quantity, etc. The number of items on this list grows. A person’s weight cannot be compared to another person’s height because one can only compare two exact quantities. Consequently, there needs to be a standard point of comparison at all times.

A common yardstick or method for assessing quantities is also required. Among them are proportion and ratio. The comparison between two quantities in terms of ratio and proportion can be taught to students. The NCERT Solutions for Class 8 Maths Chapter 8 Exercise 8.2 will teach students all there is to know about comparing various quantities.

Comparing amounts refers to the quantitative relationship between two quantities that captures their respective sizes. It is merely a method for comparing quantities.

### NCERT Solutions for Class 8 Exercise 8.2 Solutions – Brief Overview

The units of the two quantities must be the same in order to compare them. When two ratios are converted into like fractions, they can be compared. It is said that the two specified ratios are equivalent if the two fractions are equal. The four quantities involved will be in proportion if two ratios are equivalent (or equal). The formulas for ratio, proportion, and Comparing Quantities are explained in this article. Additionally, it aids in the resolution of proportional and ratio issues.

A number line can be used to teach children the importance of understanding the order of numbers when teaching them how to compare two or more items. Students can practise counting objects once the sequence of numbers can be seen.

Comparing quantities, as is known, is the quantitative relationship between two quantities that reflects the relative sizes of both quantities. It is merely a tool for comparing quantities. In order to determine if one quantity is more than, smaller than, or equal to another, it is necessary to compare the differences between the two numbers, quantities, or values.

Here is an overview of the main concepts in the NCERT Solutions for Class 8 Maths Chapter 8 Exercise 8.2:

• The units of two quantities must match in order to compare them.
• • By transforming two ratios into similar fractions, two ratios can be compared. We say that the two specified ratios are equivalent if the two fractions are equal.
• • Four quantities are said to be in proportion if two ratios are equivalent (or equal).
• • Percentage comparisons of amounts are one method of comparison. The word “percent” is derived from the Latin “per centum,” which means “per hundred.”
• • The symbol %, which also stands for percent, denotes a hundredth.
• • Percentages can be changed into fractions and vice versa.
• Additionally, decimals can be changed into percentages and vice versa.
• • An item’s cost price is its price at the time of purchase. It is abbreviated as CP.
• The selling price, or SP for short, is the cost at which an object is sold.
• • If CP > SP, a profit is made, and profit = CP SP.
• • There is no gain or loss if CP Equals SP.
• • If CP>SP, a loss is created, and Loss = CP-SP.
• Profit per cent = Profit ×100 CP
• Loss per cent = Loss ×100
• Principal (P) is short for borrowed funds.
• • “Interest” I is the additional payment made by the borrower for using borrowed funds for a specific period of time.
• “Time Period” T is the name of the duration for which the loan is made.
• ‘Rate of Interest’ to determine the amount of interest to be paid.
• The rate of interest is often expressed as a percentage per year.
• The total money paid alongwith interest or principal P is called the amount (A). Thus A = P + I.
