need help I need to have my answer in cups:

2cups N
______ ______
7 people 46 people

I did the top part right 2x46/7=13.1428
but i need to turn it into cups...13 and ___ cups.. don't know how to change the end number to cups...

  • math -

    The answer is 13 1/7 (or 92/7) , and is already in units of cups.

    It could also be written 6/7 gallon.
    (One gallon = 16 cups)

  • math -

    how do u get the 1/7? i cant figure out how to get it

  • math -

    91/7 is 13.
    92/7 is 13 with 1/7 left over.

    You might also recognize that, in the decimal form, 0.1428... = 1/7

  • math -

    sorry still stuck.. how do you do the math to get the 1/7

    0.1428 what did u do or how do u know this number is 1/7

    i don't know where you got 91/7 either..can you show me how to write it on paper so i could figure it out.

  • math -

    92/7 = 13 remainder 1

    because 13 * 7 = 91
    **1_3_______
    7/92
    **7x
    ----
    **22
    **21
    ----
    ***1
