5/6 - 3/5

To subtract fractions, we need to have a common denominator. In this case, the lowest common multiple (LCM) of 6 and 5 is 30.

So, we need to convert both fractions to have a denominator of 30:

5/6 = (5/6) x (5/5) = 25/30

3/5 = (3/5) x (6/6) = 18/30

Now, we can subtract them:

25/30 - 18/30 = 7/30

Therefore, 5/6 - 3/5 = 7/30.
