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.
