Express one quantity as a percentage of another quantity

To express one quantity as a percentage of another quantity, follow these steps:

Step 1:

Divide the quantity you want to express as a percentage by the total quantity.

For example, if you have 20 apples and you want to express 5 of them as a percentage of the total 20, you would divide 5 by 20: 5/20 = 0.25.

Step 2:

Multiply the result by 100 to get the percentage.

In the example above, 0.25 multiplied by 100 equals 25. Therefore, 5 apples is 25% of 20 apples.

Step 3:

Write the answer in the correct form, including the percent sign.

In the example above, the answer would be: "5 apples is 25% of 20 apples."

So, to express one quantity as a percentage of another quantity, you need to divide the quantity you want to express by the total quantity, then multiply by 100 and add the percent sign.
