can someone please explain/show how to do this? im really stuck with fractions

5 1/3 + (-3 9/18)

thanks so much

  • math -

    9 / 18 = 1 / 2

    3 9 / 18 = 3 1 / 2


    3 * 18 = 54


    1 / 3 = 18 / 54


    1 / 2 = 27 / 54


    5 1 / 3 + ( - 3 9 / 18 ) =

    5 1 / 3 - 3 9 / 18 =

    5 1 / 3 - 3 1 / 2

    5 + 18 / 54 - ( 3 + 27 / 54 ) =

    5 - 3 + 18 / 54 - 27 / 54 =

    2 - 9 / 54 =

    2 - 9 / ( 9 * 6 ) =

    2 - 1 / 6 =

    1 + 1 - 1 / 6 =

    1 + 6 / 6 - 1 / 6 =

    1 + 5 / 6 =

    1 5 / 6

  • math -

    1st of all its easier if u turn the fractions to improper frac.
    16/3- 63/18

    then, u get the least common ddenominator which is 18
    then,your equation should be
    96/18- 63/18
    then subtract since the 2nd fraction is negative.... and you get 33/18 or 1 and 5/6
    hope this helped:)
