What is a Percentage?
A percentage is a way of expressing a number as a fraction of 100. It is often denoted using the percent sign (%). For example, if you have 50 out of 100, this can be expressed as 50%.
Calculating a percentage involves two primary components: the part and the whole. The part is the quantity you are interested in (in our case, 24), and the whole is the total amount (which is 30).
Calculating 24 out of 30 as a Percent
To convert 24 out of 30 into a percentage, we can follow a straightforward formula:
[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]
By applying our numbers:
[ \text{Percentage} = \left( \frac{24}{30} \right) \times 100 ]
Now, let’s break this calculation down step-by-step:
-
Divide the part by the whole: [ \frac{24}{30} = 0.8 ]
-
Multiply the result by 100 to convert it into a percentage: [ 0.8 \times 100 = 80% ]
Hence, 24 out of 30 is equal to 80%! 🎉
