A simple step by step solution for calculating 84 is what percent of 400

We already have our first value 84 and the second value 400. 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 = 84/400

By multiplying both numerator and denominator by 100 we will get:

STEP 2Y = 84/400 × 100/100 = 21/100

STEP 3Y = 21

Finally, we have found the value of Y which is 21 and that is our answer.

If you want to use a calculator to find 84 is what percent of 400, simply enter 84 ÷ 400 × 100 and you will get your answer which is 21

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 84 cookies from those, and you ended up eating 400 of them! What percent of the cookies have you eaten?

Answer: 21 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 84 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.

84/400 = 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:

84/400 × 100/100 = 21/100

21 = Percent

And that means you ended up eating 21 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% / 84

Step 2: Drop the percentage marks to simplify your calculations: 100 / 400 = Y / 84

Step 3: Multiply both sides by 84 to isolate Y on the right side of the equation: 84 ( 100 / 400 ) = Y

Step 4: Computing the left side, we get: 21 = Y

This leaves us with our final answer: 84 is 21 percent of 400
