    No, it is not 1/2.

    3/10-2/5 = 3/10 - (2*2) / (5*2)

    = 3/10-4/10

    = - 1/10

    No it's not. What I would do first is get the common denominators the same. (The bottom number) So i would multiply 5 x 2 to get 10. and then you would have to do the same to the top so 2 x 2. So you would be left with 3/10 - 4/10. Which would equal - 1/10.
