One number as a percentage of another 

When you express one number as a percentage of another, you're essentially comparing the first number to the second number in terms of proportion or relative size. This is commonly used to understand the relationship between two quantities.

The formula to calculate one number as a percentage of another is:

$\text{Percentage}=\left(\frac{\text{First Number}}{\text{Second Number}}\right)\times 100\mathrm{\%}$Percentage=(Second NumberFirst Number​)×100%

For example, let's say you have 25 apples and 100 oranges. To express the number of apples as a percentage of the number of oranges, you would use the formula:

$\text{Percentage of apples}=\left(\frac{25}{100}\right)\times 100\mathrm{\%}$Percentage of apples=(10025​)×100%

$\text{Percentage of apples}=0.25\times 100\mathrm{\%}$Percentage of apples=0.25×100%

$\text{Percentage of apples}=25\mathrm{\%}$Percentage of apples=25%

So, 25 apples represent 25% of the total number of oranges.

This calculation can be used in various contexts, such as comparing the number of students who passed an exam to the total number of students, expressing a portion of a budget relative to the total budget, or determining the proportion of a population that belongs to a certain demographic group.
