    I'm sorry -- but I don't know the answers to 4, 5, and 8.

    Your first answer is correct.

    Your answers to 2 and 9 are wrong.

  • 7th grade Math quick help Ms. Sue - ,

    How come 9 is wrong? 5 goes into 31 6 times and there is 1 as the remainder so wouldn't it be 6.1?

    2. 32 slices for 16 students, so each gets 2 slices
    which is 2/8 or 1/4 of a pizza
    4. a
    5. 2.4 x 10^10
    8. 5.12 x 10–6
    9. 31/5 = 62/10 = 6.2

  • 7th grade Math quick help Ms. Sue - ,

    No. You need to carry it out as a decimal.

    With 1 as a remainder, you have the fraction of 1/5. That's 0.2. The answer is 6.2.

    Most of us use a calculator for this type of problem.

  • 7th grade Math quick help Ms. Sue - ,

    You all that are trash talking the 'cheaters' obviously don't realize how hypocritical you sound. It is like a stupid person telling another stupid person that they are stupid, it just doesn't make sense. You either had intentions of cheating yourself, or just wanted something to tattle to a teacher about.

  • 7th grade Math quick help Ms. Sue - ,

    I don't think there's anything wrong with this site but I don't think they should give the answers I think they should be patient and "help" them with there problem! Homework "help" Cause how are we supposed to know it later if we were just given the answer now. Just saying. :)

  • 7th grade Math quick help Ms. Sue - ,

    Good point Mariana. I mean it's bound to happen sometimes. Some people may not go to Connections Academy; whatever that may be. I go to the local middle school and this was my homework over break. :)
