to subtract fractions you must first convert the fractions so that they have the same denominators, then subtract the numerators from each other.
example
1/11-1/7=
common denominator = 77
1/11 * 7/7 - 1/7 * 11/11
(Note: 7/7 and 11/11 are both equal to one so the value of each fraction does not change)
7/77 - 11/77
(7-11)/77
4/77
Improved Answer:
1/11-1/7 = -4/77 because 7/77-11/77 = -4/77
