Answer :
To find 25 percent of a number, you can follow these steps:
Step 1: Understand what "percent" means. "Percent" is derived from the Latin "per centum," meaning "by the hundred." So, 25 percent means 25 out of 100.
Step 2: Convert the percent to decimal form. To convert a percentage to a decimal, divide it by 100. So, 25% becomes 25/100, which simplifies to 0.25.
Step 3: Multiply the decimal form by the number in question to find the part of the whole represented by that percentage. In this case, multiply 0.25 by 28.
Here's the calculation:
0.25 × 28 = 7
Therefore, 25 percent of 28 is 7.
The correct answer is B. 7.
