  1. 3x = 7*46

    x = 7*46/3 = 107 1/3


  2. 7 : x = 3 : 46                                      ... * 46

    46 * 7 : x = 46 * 3 : 46

    46 * 7 : x = 46 : 46 * 3

    46 * 7 : x = 3                                       ... * x

    x * 46 * 7 : x = 3 * x

    46 * 7 = 3 * x                                       ... : 3

    46 * 7 : 3 = 3 * x : 3

    46 * 7 : 3 = x

    322 : 3 = x


  3. 7/3 = x/46

    322 = 3x

    322/3 or 107.333... = x = Final Answer

  4. 7 : x

    21 : 3x

    3  : 46

    21 : 322

    3x = 322

    x = 322 / 3

  5. 46/3 = 15.333

    1:15.333 = 7:x

    15.333 x 7 = 107.333

    x = 107.333

  6. 7:107.333333 = 3:46

    take 46 and divide it by 3

    you get 15.33333 then you mulitply 15.33333 times 7

    and you get the ratio answer

  7. In a proportion, you solve by cross-multiplying. To cross multiply 7/x = 3/46, you do 7*46=3x. 3x=322, x=107 1/3
You're reading: Solve 7 : x = 3 : 46?
