**Q. percentage**

**Answer : **

Hi Deepa,

You have put only "percentage" and not specific question. So I assume that you want to understand the "percentage" concept.

Here it is :

Topic : Arithmetic - Percentage

**Concept:**

In simple terminology Percentage means out of 100

For easy understanding think like percent is made up of per cent means per 100

Example: Let understand it with few examples

- 45% means 45 out of 100 or 45/100
- 120% means 120 per 100 or 120/100
- If you say 50% of total 100 Books are in English then it means 50 out of 100 books are in English, but if total books are 200 then 50% of 200 means : (50/100) * 200 = 100 books are in English.

**Usefullness: **Percentage are quite useful in comparing items. See example below.

*Let's say A got 18 marks out of 25 and B got 35 marks out of 50. Who got better marks ?*

Just by seeing above it would be difficult to know. But if we convert to percentage it would be quite easy.

Converting A's marks into percentage 18/25 means 72/100 = 72% (multiplying numerator and denominator by 4)

Converting B's marks into percentage 35/50 means 70/100 = 70% (multiplying numerator and denominator by 2)

A got 72%

B got 70%

So we can easily find that A got better marks as 72 is higher than 70
