    go and
    find the lowest common denominator between the 4, 5 and 2
    a common multiple is 20 so..

    3x/4 - 2x/5 +x/2=

    5(3x/20)- 4(2x/20) + 10(x/20)=

    then multiply ...

    15x/20 - 8x/20 + 10x/20=__________ ???

    now add and what do you get?

  • Algebra1 -

    If the equation is:
    (3x/4) - (2x/5) + (x/2)

    Common denominator is 20
    (15x/20) - (8x/20) + (10x/20) =
    combine the three to obtain
    17x/20
