We already have our first value **20** and the second value **156**. 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 = 20156

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

STEP 2 Y = 20156 × 100100 = 12.821100

STEP 3 Y = 12.821

Finally, we have found the value of Y which is 12.821 and that is our answer.

If you want to use a calculator to find **20 is what percent of 156**, simply enter **20 ÷ 156 × 100** and you will get your answer which is **12.821**

**Question:** Your Uncle, who loves to collect antique coins, collected 20 coins from his list of 156 coins. What percent of coins has he collected?

**Question:** Your aunt has baked 156 cookies, and she gave you 20 to take home with you. What percent of the cookies did she give you?

**Answer:** 12.821 percent of the cookies.

Let's solve the equation for Y by first rewriting it as: **100% / 156 = Y% / 20**

Drop the percentage marks to simplify your calculations: **100 / 156 = Y / 20**

Multiply both sides by 20 to isolate Y on the right side of the equation: **20 ( 100 / 156 ) = Y**

Computing the left side, we get: **12.821 = Y**

This leaves us with our final answer: **20 is 12.821 percent of 156**
