# Question: What percent of 400 is 84?

Did you mean, 84 is What Percent of 400?

## Step by step method for calculating what percent of 400 is 84

We already have our first value 400 and the second value 84. 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 1 Y = 84/400

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

STEP 2 Y = 84/400 × 100/100 = 21/100

STEP 3 Y = 21

Finally, we have found the value of Y which is 21 and that is our answer. You can use a calculator to find what percent of 400 is 84, just enter 84 ÷ 400 × 100 and you will get your answer which is 21 Here is a calculator to solve percentage calculations such as what percent of 400 is 84.

## Sample questions, answers, and how to

Question: Your uncle had 400 shares of his own company a few years earlier, and now he has 84 of them. What percent of the shares of his company he has now?

Answer: He has 21 percent of shares of his company now.

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 that our uncle owned. So we put 400 on the bottom of the fraction and 84 on top. 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 he has 21 percent of the shares of his company now.

## 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: 21 percent of 400 is 84
