**subtract**123 from 16 and that equals 107/24.. if you want to convert it back to a mixed number you have to see how much 24 goes into 107 . which is 4 times, then how much remains and that would be 11. mixed fraction is 4 11/24...

If the fractions aren't in a mixed number.. heres the way to do it.

2/3 - 3/5 = 10/15 = 9/15 = 1/15 .. multiply the denominators by each other ( 5 x 3 =15) .. then cross multiply 2 x 5 = 10 and 3 x 3 = 9 .. fraction is now 10/15 and 9/15 then subtract 10 from 9 and that gives you 1/15 ..

If the fractions have different denominators

1) Find the least common denominator.

2) Find the equivalent fraction using this denominator.

3) Subtract the fractions, if you could reduce then you should.
