What is five sixth minus two fifth?

Answer 1

The Work
To do this, you must find the least common multiple of 6 and 5.
That is 30, because 6 and 5 both go into 30.
5/6 now turns into 25/30 and 2/5 is now 12/30.
Now you can subtract.
25 - 12 = 13, so now you have 13/30.
13 doesn't go into 30, so it is simplified.
