What is 25% of 400?

  1. 50

  2. 75

  3. 100

  4. 125

The correct answer is: 100

To find 25% of 400, you can use the concept of percentages as a fraction of 100. First, represent 25% as a fraction: 25% is equal to 25 out of 100, which simplifies to 1/4. This means that 25% is equivalent to one-quarter of a quantity. Next, to calculate one-quarter of 400, you can divide 400 by 4. When you divide, you get: 400 ÷ 4 = 100. This indicates that 25% of 400 is 100. Therefore, this value is the correct answer. Understanding percentages in this way can help you calculate different percentage values efficiently, as you simply need to convert the percentage to a fraction and multiply or divide as necessary.
