We already have our first value **20** and the second value **80**. 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 = 2080

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

STEP 2 Y = 2080 × 100100 = 25100

STEP 3 Y = 25

Finally, we have found the value of Y which is 25 and that is our answer.

If you want to use a calculator to find **20 is what percent of 80**, simply enter **20 ÷ 80 × 100** and you will get your answer which is **25**

**Question:** Your Uncle, who loves to collect antique coins, collected 20 coins from his list of 80 coins. What percent of coins has he collected?

**Answer:** He collected 25 percent of the coins from his list.

**Question:** Your aunt has baked 80 cookies, and she gave you 20 to take home with you. What percent of the cookies did she give you?

**Answer:** 25 percent of the cookies.

Let's solve the equation for Y by first rewriting it as: **100% / 80 = Y% / 20**

Drop the percentage marks to simplify your calculations: **100 / 80 = Y / 20**

Multiply both sides by 20 to isolate Y on the right side of the equation: **20 ( 100 / 80 ) = Y**

Computing the left side, we get: **25 = Y**

This leaves us with our final answer: **20 is 25 percent of 80**
