To reduce any fraction to its lowest terms, divide the numerator
and the denominator by their greatest common factor.
You have 36/54.
The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.
The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.
The common factors are 1, 2, 3, 6, 9, and 18.
The greatest common factor is 18 .
36 / 18 = 2
54 / 18 = 3
36/54 = 2/3
Note:
That's why you had to spend all that time doing common factors and
greatest common factor before you could go on to doing fractions.
