Understanding the Problem: What Percent of 180 is 30?

We want to find out what percentage 30 represents when compared to the whole, which is 180. In simpler terms: 30 out of 180 is what percentage?

Step-by-Step Calculation:

Here's how to solve "what percent of 180 is 30?" We will use a simple formula:

1. Set up the Equation:

The basic formula for percentage calculations is: (Part / Whole) * 100% = Percentage

In this case:

Part: 30
Whole: 180

So the equation becomes: (30 / 180) * 100% = ?

2. Solve the Fraction:

First, divide the part (30) by the whole (180):

30 / 180 = 0.166666...

3. Multiply by 100:

Now, multiply the result by 100 to convert the decimal into a percentage:

0.166666... * 100% = 16.67% (approximately)

Therefore, 30 is approximately 16.67% of 180.

Alternative Method: Using Proportions

Another way to approach this problem is using proportions. We can set up a proportion:

30/180 = x/100

Where 'x' represents the percentage we're trying to find.

To solve for 'x', cross-multiply:

180x = 3000

Then, divide both sides by 180:

x = 3000 / 180 = 16.67 (approximately)

Therefore, x = 16.67%, confirming our previous result.
