20/27 Solution Method: 40 = 2*2*2*5 (<-- these are the factors of 40) --- 54 = 2*3*3*3 (<-- these are the factors of 54) The only common factors in both the numerator & the denominator are 2. That means you can divide 40 by 2 & 54 by 2 to get 20/27.
The common factors of 12 and 54 are 1, 2, 3, and 6.
