MATH MENTOR: Finding percentages - Part 3

To review, go to Percentages Part 1
To review some more, to Percentages Part 2

Go back and review parts 1 and 2 if you are uncertain about how to use the formulas.

Finally, let's find out who to find the percentage from the whole and part amounts.

3 - Find the %

For example: I borrowed $250.00. I have paid back $187.50 of that amount. What percentage have I paid back? What percentage do I still owe?

When you have the amount of the whole and of the part, you must change the process to find the percentage they represent. The whole is 100%, of course. What about the other part?

Divide the Part by the Whole. The answer is the percentage the Part represents.

$187.50 / $ 250.00 =  .75 or 75%.

Find the part of the equation that is missing: whole, part or percent.

1. 670 = 25%

Whole?

ANSWER 670/.25 = 2680

2. 312 and 560

% ?

ANSWERS 312/560 = .557 Rounded to 56%

3.75% of 732

Part ?

ANSWER 732X.75 = 549

1. 11,300 and 3852

% ?

ANSWER 3852/11,300= .34% (rounded)

Now you have completed the circle. Keep in your memory and you'll never have trouble solving percentage problems!
