51.75 which is 52 because you tound up so it can carry approximately 52 cars because 828÷16=51.75 so it would be approximately 52
Supplementary angles will always add up to 180. If you had a straight line, and you drew another line across that line, the two angles on either side of that line would add up to 180 because a flat line is equal to 180 degrees.
If you would like to solve 9 5/9 - 6 5/6, you can calculate this using the following steps:
9 5/9 - 6 5/6 = 86/9 - 41/6 = 516/54 - 369/54 = (516 - 369) / 54 = 147/54 = 49/18 = 2 13/18
The correct result would be 2 13/18.
The answer you seek you just need to take 325 and divide it by 500 to get .65 and change .65 to 65%. And to make sure you multiply 500 by .65 to get 325.
