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
You can subtract the bigger fraction by the smaller fraction and then put a minus sign in front of the answer.
Pie charts make nice fraction diagrams. Each fraction that you subtract is equivalent to taking out a slice of pie.
Just simply add/subtract the numerators then copy the denominator.
1.1799999999999997
8/20-15/20=7/20
Change the whole number into an improper fraction with the same denominator as the fraction and then subtract accordingly

First you would want to change the mixed number to an improper fraction. Then you can subtract
In the same way that you would answer a fraction subtract another fraction. The result could be either positive or negative, just as is the case with negative whole numbers.
You can either convert the decimal to a fraction and then subtract (3/4 - 0.5 = 3/4 - 2/4 = 1/4), OR you can convert the fraction to a decimal and then subtract (3/4 - 0.5 = 0.75 - 0.5 = 0.25).
Never. You could write a fraction as a mixed fraction if you like and then the mixed fraction would have a different denominator (e.g.: 23/2 = 11 1/2)
The difference.
Turn the proper fraction into an improper fraction.

You have to get common denominators and then subtract the biggest numerator (top number) by the smallest, you may have to cnacel the fraction down to get the smallest possible fraction
It can be a negative or positive fraction, a negative or positive integer, or zero.
