Answer: The Lowest Common Denominator is 28

Explanation:

Since we need to find the lowest common denominator for the equation (-5/7, -5/4) (Respond if I'm wrong)

Step 1. Find LCM. 7: 7, 14, 21, 28, 35, ... 4: 4, 8, 12, 16, 20, 24, 28, ...

Step 2. Match LCM. 7: 7, 14, 21, 28, 35, ... 4: 4, 8, 12, 16, 20, 24, 28, ...

Step 3. Match both number to their corresponding fractions. (-5/28, -5/28). Notice how the numerator stays the same? We leave them alone, since -5 = -5.

Step 4. Match the equation. -5/28 = -5/28
