    Question precentages

    I have been trying for hours to solve this and can't figure it out!

    114 000 + 26 000
    26 000 + 40 000
    1-48%


    I can't even resolve it with my calculator?

    I've been starting with the 40 000/1-48% going to 40 000/1-0.48
    then 40 000/0.52 = 76923.07692 which is where I get in trouble. This can't be right?

    Please help ASAP as I have to turn this in pretty soon, and it's the last one I can't figure out!

    Why can't it be right? :-)

    114 000 + 26 000
    26 000 + 76923.07692

    140000
    102923.0769

    = 1.360239163 = 910/669

    Just because all the other answer of the homework were simpler, but this might be it.

    How did you get 910/669?

    Thank you for your help

    114 000 + 26 000
    26 000 + 40 000
    ..............1-0.48

    Let's take the nested fraction and deal with it separately

    40000
    ....0.52

    = 4000000
    .......52

    Now reduce to lowest terms:

    1000000
    .......13

    Put it back where it belongs now:
    114 000 + 26 000
    26 000 + 1000000
    ................13

    Combine 26000 with the fraction (and add up the numerator on your way too)
    140000
    1338000
    13

    This is actually equal to:

    140000 x (13/1338000)

    1820000/1338000

    = 1820/1338

    Reduce to lowest terms:

    910/669

    Thank you so much. I'm moving into more advance algebra, I hope you'll still be there to help me out, as I'm sure to run into some problem there.

    I'm taking this math class so that I can start my business certificate (and eventually get a University diploma). I haven't done math in 20 years, I used to be pretty good at it, but 20 years do make a difference. Hopefully, whatever brain cell are in charge of math, they'll wake up and get busy again!

    Have a great week!
