    [Easy +rep] 7th Grade - Pre-Algebra [Updated Every time I feel lazy]

    Though Math is my best grade (A+) it feels unnecessary to do the homework. This thread will be updated every time i feel lazy.
    Reps will be given to those who give the correct answers and show their work in format.

    Format Example
    (10 x 5)5 x 9
    = (50 x 5) x 9
    = 250 x 9
    = 2250





    Problems of the Day ~
    None. Reps awarded for the day. Stay tuned.




    Thanks

    x/100=80/10
    80x=1000
    Divide Both Sides by 80
    x= 12.5
    So 10 is 12.5 Percent of 80

    O:
    I can't wait til the next time this is updated.
    I love(d) Pre-Algebra, Algebra I, Algebra II, and College Algebra.
    Now I've taken every Algebra course I can until I actually go off to college. D:
    ENJOY IT WHILE YOU CAN, IT MAY BE MATH, BUT IT'S THE BEST KIND OF MATH.
    GEOMETRY AND TRIG ARE THE DEVIL.
