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
