When faced with the fraction 2/12, the first step is to reduce it to its simplest form. This process involves finding the greatest common divisor (GCD) of the numerator and denominator.

• 2/12 can be simplified by dividing both numbers by their GCD, which is 2:
  • 2 ÷ 2 / 12 ÷ 2 = 1/6

This simplification tells us that 2/12 and 1/6 are equivalent, which is our first interesting fact:

🔍 Interesting Fact #1: Reducing 2/12 to 1/6 immediately shows us that this fraction represents a simple division, where 1 is divided by 6.
