What is Meant by Percentage?
In Mathematics, a percentage is a dimensionless number. It is a ratio or a number that is expressed as a fraction of 100. The symbol used to denote percentage is the percentage sign (%). Some of the abbreviations used are pct or pc. Generally, the percentage is used to express the proportionate part of the total number.
For example, 55% can be written as 55/100, or it can be expressed as 55:100 or 0.55.
The formula to calculate the percentage is given by

Percentage, % = (Value/Total value) ×100 |

20 is what percentage of 40? Solution We know that Percentage, % = (Value/Total value) ×100 Therefore, percentage = (20/40) ×100 = 2000/40 = 50% Hence, 20 is 50% of 40. |
| Example 2: |

What is 10% of 50? Solution: We know that Percentage, % = (Value/Total value) ×100 Let value = b and total value = a Hence, the formula becomes, p% = b/a Now, we have to find “b” Substitute the values in the formula, 10% = b/50 (10%) × 50 = b b = 0.1 x 50 b = 5 Hence, 10% of 50 is 5. |

5 is 65% of what? Solution: We know that Percentage, % = (Value/Total value) ×100 Let value = b and total value = a Hence, the formula becomes, p% = b/a Now, we have to find “a” Substitute the values in the formula, 65% = 5/a a = 5 / 65% a = 7.69 Hence, 5 is 65% of 7.69. |
| Example 4: |
|---|
|
What percentage of 70 is 8? Solution: We know that p% = b/a Where a and b are numbers Here a is 70 and b is 8 Hence, p% = 8/70 = 0.114 For converting decimal to a percentage, multiply the decimal by 100 p% =0.11428 x 100 p% = 11.428% Hence 11.428% of 70 is 8. |
| Example 5: |
|---|
|
64% of what is 9? Solution: We know that p% = b/a Where a and b are numbers Now, we have to find a Here b is 9 and p% is 64% Hence, a = b/p% a = 9/64% a = 9/ 0.64 a = 14.0625 Hence, 64% of 14.0625 is 9. |
