16 ÷ 21 × 100

= (16 × 100) ÷ 21

= 1600 ÷ 21

= 76.19

**Now we have: 16 is what percent of 21 = 76.19%**

Here is a calculator to solve percentage calculations such as 16 is what percent of 21. You can solve this type of calculation with your values by entering them into the calculator's fields, and click *'Calculate'* to get the result and explanation.

We already have our first value **16** and the second value **21**. 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 = 1621

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

STEP 2Y = 1621 × 100100 = 76.19100

STEP 3Y = 76.19

Finally, we have found the value of Y which is 76.19 and that is our answer.

If you want to use a calculator to find **16 is what percent of 21**, simply enter **16 ÷ 21 × 100** and you will get your answer which is **76.19**

**Question:** You have found your auntâ€™s freshly baked cookies vault which, she just baked! She told you not to eat more than 16 cookies from those, and you ended up eating 21 of them! What percent of the cookies have you eaten?

**Answer:** 76.19 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.

PartTotal = Percent

In this case, it's the Total of those cookies that your aunt's baked. So we put 16 on top and 21 on the bottom of the fraction, and now we're ready to figure out the part we don't know; the Percent.

1621 = 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:

1621 × 100100 = 76.19100

76.19 = Percent

And that means you ended up eating 76.19 Percent of the cookies that she baked.

**Step 1:** Let's solve the equation for Y by first rewriting it as: **100% / 21 = Y% / 16**

**Step 2:** Drop the percentage marks to simplify your calculations: **100 / 21 = Y / 16**

**Step 3:** Multiply both sides by 16 to isolate Y on the right side of the equation: **16 ( 100 / 21 ) = Y**

**Step 4:** Computing the left side, we get: **76.19 = Y**

This leaves us with our final answer: **16 is 76.19 percent of 21**
