We already have our first value 81 and the second value 90. 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 = 8190
By multiplying both numerator and denominator by 100 we will get:
STEP 2 Y = 8190 × 100100 = 90100
STEP 3 Y = 90
Finally, we have found the value of Y which is 90 and that is our answer.
If you want to use a calculator to find 81 is what percent of 90, simply enter 81 ÷ 90 × 100 and you will get your answer which is 90

Question: Your Uncle, who loves to collect antique coins, collected 81 coins from his list of 90 coins. What percent of coins has he collected?
Answer: He collected 90 percent of the coins from his list.
Question: Your aunt has baked 90 cookies, and she gave you 81 to take home with you. What percent of the cookies did she give you?
Answer: 90 percent of the cookies.
Let's solve the equation for Y by first rewriting it as: 100% / 90 = Y% / 81
Drop the percentage marks to simplify your calculations: 100 / 90 = Y / 81
Multiply both sides by 81 to isolate Y on the right side of the equation: 81 ( 100 / 90 ) = Y
Computing the left side, we get: 90 = Y
This leaves us with our final answer: 81 is 90 percent of 90
