Step 1: Calculate the greatest common divisor (GCD):
20 ÷ 100 = 0 Remainder 20
100 ÷ 20 = 5 Remainder 0
The Greatest Common Divisor (GCD) of 20 and 100 is 20.
Step 2: Simplifying by the greatest common divisor (GCD):
Since the GCD is greater than 1, the fraction can be simplified directly to lowest terms by this number (20):
|20||=||20 ÷ 20||=||1|
|100||100 ÷ 20||5|
