can someone help me with subtracting variable fractions? 4m/5 - 9m/11

Subtracting variable fractions works the same way that subtracting regular fractions works, as in that you must find a common denominator. Do this by multiplying each portion of each fraction by the denominator of the other fraction: (11/11)(4m/5) - (5/5)(9m/11) 44m/55 - 45m/55 = -1m/55
