How do you determine part and whole in percent problems?
Part/Whole = Percent/100 ⇒ Part/50 = 10/100 ⇒ Part = 5. Therefore, 10% of 50 is 5….It is expressed in form of PART/WHOLE = PERCENT/100, where,
- PERCENT is the number with a percent sign.
- PART is the number with the word IS.

How to find the answer to the percent problem?
When you have an equation such as 20% ·n = 30, you can divide 30 by 20% to find the unknown: n= 30 ÷ 20%. You can solve this by writing the percent as a decimal or fraction and then dividing. n= 30 ÷ 20% = 30 ÷ 0.20 = 150 You can estimate to see if the answer is reasonable.
How is the amount related to the percent?
The amount is the number that relates to the percent. It is always part of the whole. In the problem above, the amount is unknown. Since the percent is the percent off, the amount will be the amount off of the price. You will return to this problem a bit later.

How are fractions and percents related in math?
An equation uses an equal sign (=) to show that two mathematical expressions have the same value. Percents are fractions, and just like fractions, when finding a percent (or fraction, or portion) of another amount, you multiply. The percent of the base is the amount. Percent of theBase is theAmount.
