∙ 2010-01-29 04:13:42Divide 100 by the known percentage and multiply the result by the known part. This will calculate the whole. Example: £10 is equal to 25%. Thus the whole = (100/25) * 10 = £40.
Divide the numerator into the denomonator.
To find percents, divide the whole by 100 and multiply by percent rate. For this question, the example problem and solution will be:Problem: find 14 percent of 1600Solution: 1600 / 100 * 14 = 16 * 14 = 224
1 whole = 100 percent. 1 fifth = (1 whole)/5 = (100/5) = 20 percent.
306.25 rounded to the nearest whole is 306. As a percent, that is 30600%
Divide (the known part) by (the percent). The quotient is the whole unknown number.
Divide the amount given as a percent of a whole by the percent, converted to a decimal by multiplying the percent by 0.01 (exact). The value of the whole will be the quotient. In symbols, when w is the unknown whole, k is a known percent of the whole, and the percent p itself is known, w = k/(0.01)p or 100 (k/p).
Part = Whole*Percent/100
Divide 100 by the known percentage and multiply the result by the known part. This will calculate the whole. Example: £10 is equal to 25%. Thus the whole = (100/25) * 10 = £40.
You find the percentage equivalent and the round the result to the nearest whole number.

I'm not sure
Divide the percent into 100 then multiply the result by the number that is that percent of the whole. For example, if 25% of your weekly wage is $65, then... 100 divided by 25 is 4. 4 times $65 = $260.
To find the percentage, subtract the part to the whole . Take your answer and divide it into the whole. Then multiply by 100.
part over whole
divide the part, by the whole, then multiply your answer by 100
Divide the numerator into the denomonator.
