We need to find a common denominator to add and subtract the fractions. The smallest common multiple of 4, 5, and 10 is 20.
1/4 can be written as 5/20, 3/5 can be left as is, and 3/10 can be written as 6/20.
So, the expression becomes:
5/20 + 3/5 - 6/20
Combining the numerators with the common denominator, we get:
(5 + 12 - 6)/20 = 11/20
Therefore, the solution is:
1/4 + 3/5 - 3/10 = 11/20
