  1. If the three numbers are x,y,z, then we know that

    y = 2x
    y = 3z
    (x+y+z)/3 = 44

    Now just find z.

  3. clear the fraction, and you have

    x+y+z = 3*44 = 132

    Now, since y=2x=3z,
    2x=3z, and x = 3z/2

    Now just add them up and you have

    3z/2 + 3z + z = 132
    11z/2 = 132
    z = 132 * 2/11 = 24
