You don't need to convert it to improper fraction to solve.

snowcrystal · Answer

it should end up being $$\frac{ 13 }{ 10 } or                     1 \frac{ 3 }{ 10 }$$

hero · Answer

How to do it without converting to improper fraction:

Subtract the whole numbers then subtract the fractions:

(2 - 1) + (4/5 - 1/2)

2 - 1 + 8/10 - 5/10

1 + 3/10
