We already have our first value **13.5** and the second value **45**. 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 = 13.545

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

STEP 2 Y = 13.545 × 100100 = 30100

STEP 3 Y = 30

Finally, we have found the value of Y which is 30 and that is our answer.

If you want to use a calculator to find **13.5 is what percent of 45**, simply enter **13.5 ÷ 45 × 100** and you will get your answer which is **30**

**Question:** Your Uncle, who loves to collect antique coins, collected 13.5 coins from his list of 45 coins. What percent of coins has he collected?

**Answer:** He collected 30 percent of the coins from his list.

**Question:** Your aunt has baked 45 cookies, and she gave you 13.5 to take home with you. What percent of the cookies did she give you?

**Answer:** 30 percent of the cookies.

Let's solve the equation for Y by first rewriting it as: **100% / 45 = Y% / 13.5**

Drop the percentage marks to simplify your calculations: **100 / 45 = Y / 13.5**

Multiply both sides by 13.5 to isolate Y on the right side of the equation: **13.5 ( 100 / 45 ) = Y**

Computing the left side, we get: **30 = Y**

This leaves us with our final answer: **13.5 is 30 percent of 45**
