If you have the question “4 is what percent of fifty?” then you know that a percentage is one-hundredth of a whole number. However, you may not be as familiar with the math behind percentages. This article will explain how to calculate the percentage of a number. This article will help you understand how to solve word problems that involve percentages. If you are unable to solve a problem using a single number, you can use a calculator to calculate the answer.
To understand percentages, you need to first know how to use fractions and decimals. Consider this example: If 100 apples are bad, then 15% of them are bad. However, if there are only two hundred apples, then only twenty-five percent of them will be bad. Therefore, 25% of the apples are bad. Similar to the above, only five percent of bad apples can be found in a hundred good apples.
