The way to take a percent of a number is Devide the percentage by 100. Take that number and multiply it by what you are taking the percentage of. So in this case: 20/100=0.2 9900*.2=1980 1980 is your answer
9930 rounded to the nearest 100? I can explain it. If we are figuring the nearest 100, we have to look at the tens and ones. 30 is way lower than 49, so it rounds down to 9900. Hope you got it.
