    You gotta love multiple choice questions where none of the answers work!

    -15/35 = -.42857

    2.39 = 239 / 100 --can't be reduced!

    the answer for first one----15/35=(3x5)/(5x7)=3/7=0.428571

    the answer for second is----either option 2 or 3 because---23/10 is 2.3 & 12/5 is 3.4 which are approximately correct & also close to 2.39. That's it!

    -5/35 = -.4285714286

    2.39 = 2 39/100 = 239/100

    I don't know what's going on with those questions, but for neither is there a correct option to choose.

    Anyway, the first answer is -0.42857 and the second 239/100.
