Question: You have found your aunt’s freshly baked cookies vault which, she just baked! She told you not to eat more than 100 cookies from those, and you ended up eating 400 of them! What percent of the cookies have you eaten?

Answer: 25 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 100 on top and 400 on the bottom of the fraction, and now we're ready to figure out the part we don't know; the Percent.

100/400 = 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:

100/400 × 100/100 = 25/100

25 = Percent

And that means you ended up eating 25 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% / 400 = Y% / 100

Step 2: Drop the percentage marks to simplify your calculations: 100 / 400 = Y / 100

Step 3: Multiply both sides by 100 to isolate Y on the right side of the equation: 100 ( 100 / 400 ) = Y

Step 4: Computing the left side, we get: 25 = Y

This leaves us with our final answer: 100 is 25 percent of 400
