    (2) 175.
    3/7 of 350 is 150
    1/4 of 150 is 37.5
    2/5 of 37.5 is 15

    1/2 of 350 is 175
    Thanks for giving us options smile

    2/5 * 1/4 * 3/7 * x = 15
    6/140 * x = 15
    3/70 * x = 15
    3x = 15 * 70
    3x = 1050
    x = 1050/3
    x = 350

    Half of 350 = 175!! (Which is number 2, same as above!)

    Took me a while to figure it out but I finally did smile

    (2/5)(1/4)(3/7) = 6/140 = 3/70

    (3/70)x = 15, then x = 350

    half of x is 175.

    Answer is (2) 175
    2/5 * 1/4 * 3/7 * x= 15
    x=350
    350/2=175
    therefore answer is 175.
