Question: Your uncle had 30 shares of his own company a few years earlier, and now he has 15 of them. What percent of the shares of his company he has now?

Answer: He has 50 percent of shares of his company now.

How To: The key words in this problem are "What Percent" because they let us know that it's the Percent that is missing. So the two numbers that it gives us must be the "Total" and the "Part" we have.

Part/Total = Percent

In this case, it's the Total that our uncle owned. So we put 30 on the bottom of the fraction and 15 on top. Now we're ready to figure out the part we don't know; the Percent.

15/30 = Percent

To find the percent, all we need to do is convert the fraction into its percent form by multiplying both top and bottom part by 100 and here is the way to figure out what the Percent is:

15/30 × 100/100 = 50/100

50 = Percent

And that means he has 50 percent of the shares of his company now.

Another step by step method

Step 1: Let's solve the equation for Y by first rewriting it as: 100% / 30 = Y% / 15

Step 2: Drop the percentage marks to simplify your calculations: 100 / 30 = Y / 15

Step 3: Multiply both sides by 15 to isolate Y on the right side of the equation: 15 ( 100 / 30 ) = Y

Step 4: Computing the left side, we get: 50 = Y

This leaves us with our final answer: 50 percent of 30 is 15

If it's not what You are looking for type in the calculator fields your own values, and You will get the solution.

To get the solution, we are looking for, we need to point out what we know. 1. We assume, that the number 30 is 100% - because it's the output value of the task. 2. We assume, that x is the value we are looking for. 3. If 100% equals 30, so we can write it down as 100%=30. 4. We know, that x% equals 15 of the output value, so we can write it down as x%=15. 5. Now we have two simple equations:1) 100%=302) x%=15where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:100%/x%=30/156. Now we just have to solve the simple equation, and we will get the solution we are looking for.7. Solution for 15 is what percent of 30100%/x%=30/15

(100/x)*x=(30/15)*x - we multiply both sides of the equation by x

100=2*x - we divide both sides of the equation by (2) to get x100/2=x 50=x x=50now we have:

15 is 50% of 30

Question: What is 15 percent of 30?

We need to determine 15% of 30 now and the procedure explaining it as such

Step 1: In the given case Output Value is 30.

Step 2: Let us consider the unknown value as x.

Step 3: Consider the output value of 30 = 100%.

Step 4: In the Same way, x = 15%.

Step 5: On dividing the pair of simple equations we got the equation as under

30 = 100% (1).

x = 15% (2).
