Hello, I need a little assistance with showing my work on this question. The equation is -4 7/8 x 2/3. I have to explain how this person is wrong then show the work the correct way. Okay so the person's work is written as, "-4 7/8 x 2/3 = -4 14/24 = -4 7/12" So, I have to explain how that's wrong and what mistakes were made then provide the answer and the work. I've figured out the answer, 3 11/12. I just need assistance with showing my work. Please. :)

  1. Steve

    -4 7/8 = -(4 + 7/8)
    so, (-4 7/8)(2/3) = -4(2/3) - (7/8)(2/3)

    the example shown forgets to multiply the 4 by 2/3

    3 11/12 is also wrong, most clearly because it is not negative. How did you arrive at that answer? How can you possibly need assistance in showing your own work?

    Oh my god. I said the wrong answer.

  3. @LittleMsAmelia

    I meant to write it as negative and I accidentally wrote my answer to the previous answer and the answer I got is 3 1/4. I don't really understand how to show my work with multiplying fractions so I'm going to be honest I calculated my answer with a calculator now I just needed assistance with showing my work so I can get full credit. :/

    -4 7/8 = -39/8

    (-39/8)(2/3) = -78/24 = -13/4 = -3 1/4
