We already have our first value **4** and the second value **10**. 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 = 410

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

STEP 2 Y = 410 × 100100 = 40100

STEP 3 Y = 40

Finally, we have found the value of Y which is 40 and that is our answer.

If you want to use a calculator to find **4 is what percent of 10**, simply enter **4 ÷ 10 × 100** and you will get your answer which is **40**

**Question:** Your Uncle, who loves to collect antique coins, collected 4 coins from his list of 10 coins. What percent of coins has he collected?

**Answer:** He collected 40 percent of the coins from his list.

**Question:** Your aunt has baked 10 cookies, and she gave you 4 to take home with you. What percent of the cookies did she give you?

**Answer:** 40 percent of the cookies.

Let's solve the equation for Y by first rewriting it as: **100% / 10 = Y% / 4**

Drop the percentage marks to simplify your calculations: **100 / 10 = Y / 4**

Multiply both sides by 4 to isolate Y on the right side of the equation: **4 ( 100 / 10 ) = Y**

Computing the left side, we get: **40 = Y**

This leaves us with our final answer: **4 is 40 percent of 10**
