The sum of three numbers is 92. The first number is 1/3 of the second, and the second is 2/5 of the third. What is the second number?

  • math -

    third --- x
    second --- (2/5)x = 2x/5
    first ----- (1/3)(2x/5) = 2x/15

    x + 2x/5 + 2x/15 = 92
    times 15
    15x + 6x + 2x = 1380
    x = 60

    third = 60
    second = 24
    first = 8
