My answer is 1200-1000=200

200/1200= 1/6 ( some wrong )

  • maths -

    That's not the answer I got when I divided 200 by 1200.

    You need to find the decimal answer. Use a calculator.

  • maths -

    the decimal answer is 0.1666666

  • maths -

    Right.

    To find the percent, multiply:

    0.1666666 * 100 = 16 2/3%

    oh, I get it now, thank you

    Yay! :-)

    You're welcome.
