Answer

Follow these steps:

Step 1: If the denominator is negative, multiply both numerator and denominator by -1

Step 2: Find the GCD (Greatest Common Divisor) of the numerator and denominator

Step 3: Divide both numerator and denominator by their GCD

Example: Convert -8/28 to standard form

  • GCD(8, 28) = 4
  • -8 ÷ 4 = -2
  • 28 ÷ 4 = 7
  • Standard form: -2/7
