Understanding the Basics of Percentages

Before we dive into the calculation, let’s review the basic formula for finding a percentage:

[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]

In this case, Part is the numerator (18), and Whole is the denominator (30).

Step 1: Setting Up the Equation

To find the percentage for the fraction 18/30, set up the equation:

[ \text{Percentage} = \left( \frac{18}{30} \right) \times 100 ]

This tells us we need to divide 18 by 30 and then multiply the result by 100.

Step 2: Dividing the Numbers

Now we perform the division:

[ \frac{18}{30} = 0.6 ]

This means that 18 is 0.6 of 30.

Step 3: Multiplying by 100

Next, multiply the result by 100 to convert it into a percentage:

[ 0.6 \times 100 = 60% ]

Thus, the final result is that 18 out of 30 is equivalent to 60%. 🎉
