To get a percentage, the general formula is:

Percentage=(PartWhole)×100\text{Percentage}=\left(\frac{\text{Part}}{\text{Whole}}\right)\times 100Percentage=(WholePart​)×100

This means you divide the part (the portion or subset of the whole) by the total (whole), then multiply the result by 100 to convert it to a percentage. For example, if there are 26 boys in a class of 50 students, the percentage of boys is:

2650×100=52%\frac{26}{50}\times 100=52%5026​×100=52%

Methods to Calculate Percentage:

• You can convert a fraction to a percentage by multiplying it by 100.
• If given a decimal, multiply it by 100 to get the percentage.
• You can also find percentages mentally by breaking them into parts like 1%, 10%, and 50%.

Basic Use Cases:

• To find what percent one number is of another.
• To find a percentage of a number.
• To calculate percentage change.

This formula and approach work for many practical scenarios including grades, discounts, statistics, and more.
