Worked Examples

Example 1: Adding Negative Fractions

Let's add -1/2 and -3/4:

Convert fractions to decimals: -1/2 = -0.5, -3/4 = -0.75
Perform the addition: -0.5 + (-0.75) = -1.25
Convert the result back to a fraction: -1.25 = -5/4

The result is -5/4 or -1.25.

Example 2: Multiplying Positive and Negative Fractions

Let's multiply 3/4 and -2/3:

Convert fractions to decimals: 3/4 = 0.75, -2/3 ≈ -0.6667
Perform the multiplication: 0.75 × (-0.6667) ≈ -0.5
Convert the result back to a fraction: -0.5 = -1/2

The result is -1/2 or -0.5.
