Understanding Percentages

Before we dive into the calculation, let's quickly review what percentages represent. A percentage is a fraction expressed as a number out of 100. For example, 3.5% means 3.5 out of 100, or 3.5/100.

Method 1: Converting the Percentage to a Decimal

This is the most common and straightforward method. We'll convert the percentage to a decimal and then multiply it by the number.

Step 1: Convert the percentage to a decimal.

To convert 3.5% to a decimal, divide it by 100:

3.5% / 100 = 0.035

Step 2: Multiply the decimal by the number.

Now, multiply the decimal by 150,000:

0.035 * 150,000 = 5250

Therefore, 3.5% of 150,000 is 5250.

Method 2: Using Fractions

This method involves converting the percentage to a fraction and then multiplying.

Step 1: Convert the percentage to a fraction.

3.5% can be written as 3.5/100. To simplify this fraction, we can multiply both the numerator and denominator by 10 to remove the decimal:

(3.5 * 10) / (100 * 10) = 35/1000

We can further simplify this fraction by dividing both the numerator and denominator by 5:

35/1000 = 7/200

Step 2: Multiply the fraction by the number.

Now multiply the simplified fraction by 150,000:

(7/200) * 150,000 = 7 * (150,000/200) = 7 * 750 = 5250

Again, we find that 3.5% of 150,000 is 5250.
