-66 over -99 into a graph?

  1. Mar 11, 2016 #1
    Okay, so I'm down to the last equation.

    -12/11 x 10 + 54/11 I get -66/-99. Is this right? If so how do I put it into the graph.

    -12/11 x 10 = -120/110 + 54/11 = -66/99 (I think I've went wrong somewhere)

    -12/11 x 10 is not -120/110.
    What would happen if you reduced -120/110? You'd get -12/11. :smile:

    I forget to reduce! :nb)

    So I pretty much skip over multiplying -12/11 by 10 and just do -12/11 + 54/11? I get 42/11 somehow... I can't graph that. :frown:

    EDIT: Sorry I calculated it incorrectly. I think it's 42/0 which is 0

    No. Multiply -12/11 by 10.

    How do you multiply a fraction?
    A simple example: 1/3 x 2 will equal what?

    2/3? o_O

    2/6 is still 1/3.

    If you have 1/3 of a cup of milk in a glass, and you add another 1/3 (i.e. x2), how much milk is in your glass?

    Sorry, that was a quick response. I realized it quickly and changed it.

    So I should do -12/11 x 10 = -120/11?

    :biggrin:

    (For future reference, you cannot add two fractions unless they have a common denominator, so the fact that you were trying to add 110ths to 11ths should be a tip-off.)

    I got the answer, it's -3! Sorry sometimes I make really silly mistakes. ?:)

    EDIT: Nope it was -6... went wrong somewhere again...

    They're not silly mistakes. If you make no mistakes, you're in a class that's too easy for you. :wink:
