Understanding Percentages

A percentage is a fraction expressed as a number out of 100. The term "percent" literally means "out of one hundred" (per centum in Latin). So, 3.035. Worth adding: to represent this as a decimal, we divide 3. 5 by 100, which gives us 0.5% can be understood as 3.5 out of every 100. This decimal representation is crucial for performing percentage calculations.

Method 1: Using Decimal Conversion

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

Steps:

1. Convert the percentage to a decimal: Divide 3.5 by 100: 3.5 / 100 = 0.035

2. Multiply the decimal by the number: Multiply 0.035 by 140,000: 0.035 x 140,000 = 4900

Because of this, 3.5% of 140,000 is 4900.

Method 2: Using Fractions

Percentages can also be expressed as fractions. Day to day, 3. 5% can be written as 3.5/100, which simplifies to 7/200. This fractional representation allows for an alternative calculation method.

Steps:

1. Express the percentage as a fraction: 3.5% = 3.5/100 = 7/200

2. Multiply the fraction by the number: (7/200) x 140,000

3. Simplify the calculation: We can simplify this by cancelling out common factors. 140,000 divided by 200 is 700. Because of this, the calculation becomes 7 x 700.

4. Perform the multiplication: 7 x 700 = 4900

Again, we find that 3.5% of 140,000 is 4900.

Method 3: Using Proportions

This method uses the concept of ratios and proportions. We can set up a proportion to solve for the unknown value.

Steps:

1. Set up a proportion: We can represent the problem as a proportion: x/140,000 = 3.5/100

2. Cross-multiply: To solve for x, we cross-multiply: 100x = 3.5 x 140,000

3. Solve for x: 100x = 490,000. Divide both sides by 100: x = 4900

This method confirms that 3.5% of 140,000 is 4900.
