Detailed explanation-1: -In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred.

Detailed explanation-2: -Calculating the Percent In finding the percent of a number, divide the percentage by the quantity then multiply the product by 100.

Detailed explanation-3: -To find 1% of something (1/100 of something), divide by 100. Remember how to divide by 100 mentally: Just move the decimal point two places to the left. For example, 1% of 540 is 5.4. And 1% of 8.30 is 0.083.

Detailed explanation-4: -To determine totals from a percent in the future, multiply the given percentage value by 100 and divide that product by the percent. This method works in any instance where a percentage and its value are given. For example, when 2 percent = 80, multiply 80 by 100 and divide by 2 to reach 4000.

Detailed explanation-5: -To find a multiple of 10%, like 30% or 70% of a number, just divide by 10 and multiply by the numbers of tens you have. To find 30%, you divide by 10 and multiply by 3. To find 70%, divide by 10 and multiply by 7.
