We already have our first value **8.7** and the second value **87**. 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 = 8.787

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

STEP 2 Y = 8.787 × 100100 = 10100

STEP 3 Y = 10

Finally, we have found the value of Y which is 10 and that is our answer.

If you want to use a calculator to find **8.7 is what percent of 87**, simply enter **8.7 ÷ 87 × 100** and you will get your answer which is **10**

**Question:** Your Uncle, who loves to collect antique coins, collected 8.7 coins from his list of 87 coins. What percent of coins has he collected?

**Answer:** He collected 10 percent of the coins from his list.

**Question:** Your aunt has baked 87 cookies, and she gave you 8.7 to take home with you. What percent of the cookies did she give you?

**Answer:** 10 percent of the cookies.

Let's solve the equation for Y by first rewriting it as: **100% / 87 = Y% / 8.7**

Drop the percentage marks to simplify your calculations: **100 / 87 = Y / 8.7**

Multiply both sides by 8.7 to isolate Y on the right side of the equation: **8.7 ( 100 / 87 ) = Y**

Computing the left side, we get: **10 = Y**

This leaves us with our final answer: **8.7 is 10 percent of 87**
