15 ÷ 20 × 100
= (15 × 100) ÷ 20
= 1500 ÷ 20
Now we have: 15 is what percent of 20 = 75%

We already have our first value 15 and the second value 20. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 1Y = 15/20
STEP 2Y = 15/20 × 100/100 = 75/100
STEP 3Y = 75
Finally, we have found the value of Y which is 75 and that is our answer.
If you want to use a calculator to find 15 is what percent of 20, simply enter 15 ÷ 20 × 100 and you will get your answer which is 75

Question: You have found your aunt’s freshly baked cookies vault which, she just baked! She told you not to eat more than 15 cookies from those, and you ended up eating 20 of them! What percent of the cookies have you eaten?
Answer: 75 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 15 on top and 20 on the bottom of the fraction, and now we're ready to figure out the part we don't know; the Percent.
15/20 = 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:
15/20 × 100/100 = 75/100
75 = Percent
And that means you ended up eating 75 Percent of the cookies that she baked.
Step 1: Let's solve the equation for Y by first rewriting it as: 100% / 20 = Y% / 15
Step 2: Drop the percentage marks to simplify your calculations: 100 / 20 = Y / 15
Step 3: Multiply both sides by 15 to isolate Y on the right side of the equation: 15 ( 100 / 20 ) = Y
Step 4: Computing the left side, we get: 75 = Y
This leaves us with our final answer: 15 is 75 percent of 20
