Sample questions, answers, and how to

Question: You have found your aunt’s freshly baked cookies vault which, she just baked! She told you not to eat more than 20 cookies from those, and you ended up eating 280 of them! What percent of the cookies have you eaten?

Answer: 7.143 percent of the cookies that she baked.

How To: The key words in this problem are "What Percent" because they let us know that it's the Percent that is missing. So the two numbers that it gives us must be the "Total" and the "Part" we have.

Part/Total = Percent

In this case, it's the Total of those cookies that your aunt's baked. So we put 20 on top and 280 on the bottom of the fraction, and now we're ready to figure out the part we don't know; the Percent.

20/280 = Percent

To find the percent, all we need to do is convert the fraction into its percent form by multiplying both top and bottom part by 100 and here is the way to figure out what the Percent is:

20/280 × 100/100 = 7.143/100

7.143 = Percent

And that means you ended up eating 7.143 Percent of the cookies that she baked.

Another step by step method

Step 1: Let's solve the equation for Y by first rewriting it as: 100% / 280 = Y% / 20

Step 2: Drop the percentage marks to simplify your calculations: 100 / 280 = Y / 20

Step 3: Multiply both sides by 20 to isolate Y on the right side of the equation: 20 ( 100 / 280 ) = Y

Step 4: Computing the left side, we get: 7.143 = Y

This leaves us with our final answer: 20 is 7.143 percent of 280
