**Percentage as Decimals and Fractions:-** One percent is one-hundredth of an entirety. It can so compose as both a decimal and a part. To write percentage as fraction, divide by 100.

Example: half becomes 0.5, 70% becomes 0.7, 9% becomes 0.09, etc.

The best method to find the percentage. Half is equal to 50%, so 50% of 50 is 25. The decimal of half is 0.5 as half is (1/2). So another method of discovering 50% of 50 is to state 0.5 × 50 = 25. Thus Half = (1/2) = 50% = 0.5

30% of 150 is equal to stating 0.3 × 150, which rises to 45.

13.5% of 200 = 200 × 0.135, which approaches 27.

Example:

Harry's pay increment above was 10% of $30,000.

$30,000 × 0.1 = $3000. The change from decimal to rate is the converse estimation: increase your decimal by 100. 0.5 = half

0.895 = 89.5%

half = 50/100 = 5/10 = ½

90% = 90/100 = 9/10

60% = 60/100 = 6/10 = 2/5

Percentage Change (decrease and increase) :-

Percentage change from y1 to y2 calculate the formula:

percentage change = 100% × (y2 - y1) / y1

If we have the percentage increase, then the result is positive.

Example:

Percentage change from 40 to 60 (increase).

100% × (60 - 40) / 40 = 50%

If we have the percentage decrease, then the result is negative.

**Example:**
Percentage change from 60 to 40 (decrease).

100% × (40 - 60) / 60 = -33.33%
