- To convert fraction into percentage, multiply by 100.
- To convert decimal into percentage, multiply by 100 and add % sign.
- To convert percentage into decimal, divide by 100.
- To find x% of y, use (x/100) × y.
Examples:
- 1/2 = 50%
- 0.75 = 75%

Complete Study Guide for ML Aggarwal Class 8 Maths Chapter 7 Percentage
Percentage questions become simple when solved step by step. Students should first identify what is given and what is required. If the question asks for percentage of a number, use the direct formula. If it asks for increase or decrease, compare old and new values carefully. For example, if the price of a bag increases from 400 to 500, then increase = 100. Percentage increase = (100/400) × 100 = 25%. This type of question is common in exams. Similarly, if marks decrease from 80 to 72, decrease = 8. Percentage decrease = (8/80) × 100 = 10%. Students should practice such sums daily for better speed.
Exam Preparation Tips for Percentage Chapter
To score high marks in ML Aggarwal Class 8 Maths Chapter 7 Percentage, students should follow these tips:
- Memorize common fraction to percentage conversions.
- Practice decimal conversions daily.
- Revise formulas for increase and decrease.
- Solve textbook examples first.
- Check calculations carefully.
- Practice word problems from shopping and marks topics.
- Revise mistakes and attempt them again.
This chapter is highly scoring because most questions follow standard methods. With regular practice, students can solve questions quickly and accurately. Percentage is one of the most useful mathematical concepts used both in academics and real life. Students should also understand estimation methods.
