Multiply the whole by the percentage number and divide by 100.
For example, to find 30% of 90: 30 x 90 / 100 = 27.
Or change the percent to a decimal first, then multiply by the whole number.
E.g. 30% of 90= 0.30 X 90= 27
Remember: the word "OF" in math usually means multiplication!!
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).
====== Answer 1: ----------- proportion... A portion of the total is to its percentage of the total as the total is to 100%.
To find the whole when you know a part and the percent, you can use the formula: Whole = Part / (Percent / 100). First, convert the percent to a decimal by dividing it by 100. Then, divide the part by this decimal to calculate the whole. For example, if the part is 20 and the percent is 25, the whole would be 20 / (25 / 100) = 80.
When a whole number is given- divide the percent given into the whole number and you will get the original number 39\40 should equal 97.5 great fun you should try it. Works every time.
find the frequency before finding the percent total -_- :)

Part = Whole*Percent/100
how do you find a number when a percent of it is known
You find the percentage equivalent and the round the result to the nearest whole number.

You can use the equivalent form of the percent proportion, which is expressed as ( \text{part} = \text{percent} \times \text{whole} ), to solve percent problems by identifying the part (the amount you want to find), the percent (the percentage given), and the whole (the total amount). By rearranging the formula, you can solve for the unknown variable. For example, if you need to find 20% of 50, you can calculate it as ( \text{part} = 0.20 \times 50 ), leading to the solution of 10.
