Worked Examples

Let's look at some examples to see how the calculator handles negative fractions.

Example 1: Adding Negative Fractions

Calculate (-3/4) + (-1/2):

Step 1: Find a common denominator (4)

Step 2: Convert fractions: (-3/4) + (-2/4)

Step 3: Add numerators: -3 + (-2) = -5

Step 4: Result: -5/4

Example 2: Multiplying Positive and Negative Fractions

Calculate (2/3) × (-4/5):

Step 1: Multiply numerators: 2 × (-4) = -8

Step 2: Multiply denominators: 3 × 5 = 15

Step 3: Result: -8/15

Example 3: Dividing Fractions with Negatives

Calculate (-5/6) ÷ (3/4):

Step 1: Multiply by reciprocal: (-5/6) × (4/3)

Step 2: Multiply numerators: -5 × 4 = -20

Step 3: Multiply denominators: 6 × 3 = 18

Step 4: Result: -20/18 = -10/9 (simplified)

Common Mistakes

When working with fractions and negatives, several common mistakes can occur:

1. Forgetting to Find a Common Denominator

When adding or subtracting fractions, it's crucial to find a common denominator first. Skipping this step can lead to incorrect results.

2. Incorrectly Handling Negative Signs

Negative signs can be tricky, especially when multiplying or dividing fractions. Remember that a negative times a negative equals a positive.

3. Not Simplifying Fractions

Always simplify fractions to their lowest terms. This makes the results easier to understand and work with.

4. Mixing Up Numerators and Denominators

When dividing fractions, remember to multiply by the reciprocal of the second fraction. Mixing up numerators and denominators can lead to errors.
