Simplify 81/108.

Explanation:
Finding the greatest common divisor to reduce a fraction is the key. For 81/108, both numbers share 27 as a common factor, and 27 is the largest one they share. Dividing both by 27 gives 81 ÷ 27 = 3 and 108 ÷ 27 = 4, so the fraction becomes 3/4. This is in its simplest form because 3 and 4 have no common factors other than 1. You can also see the same idea by dividing by 9 first to get 9/12, then dividing by 3 to reach 3/4, arriving at the same simplest form.
