We already have our first value **45** and the second value **54**. 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 = 4554

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

STEP 2 Y = 4554 × 100100 = 83.333100

STEP 3 Y = 83.333

Finally, we have found the value of Y which is 83.333 and that is our answer.

If you want to use a calculator to find **45 is what percent of 54**, simply enter **45 ÷ 54 × 100** and you will get your answer which is **83.333**

**Question:** Your Uncle, who loves to collect antique coins, collected 45 coins from his list of 54 coins. What percent of coins has he collected?

**Question:** Your aunt has baked 54 cookies, and she gave you 45 to take home with you. What percent of the cookies did she give you?

**Answer:** 83.333 percent of the cookies.

Let's solve the equation for Y by first rewriting it as: **100% / 54 = Y% / 45**

Drop the percentage marks to simplify your calculations: **100 / 54 = Y / 45**

Multiply both sides by 45 to isolate Y on the right side of the equation: **45 ( 100 / 54 ) = Y**

Computing the left side, we get: **83.333 = Y**

This leaves us with our final answer: **45 is 83.333 percent of 54**
