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

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

maths  Tomas, Thursday, August 15, 2013 at 7:07pm
the decimal answer is 0.1666666

maths  Ms. Sue, Thursday, August 15, 2013 at 7:16pm
Right.
To find the percent, multiply:
0.1666666 * 100 = 16 2/3%
