First, 30 doesn't go into 20, so you have to fit it into 200 right away, which makes the problem a little more challenging. Note that 30 * 10 = 300, too much, and 30 * 5 = 150, too low. 30 * 9 = 270, still too high. 30 * 6 = 180. Adding another 30 would make 210, which is too high, so we go with 6. 200 - 180 = 20, which means we need to bring down a 0 from the decimals to continue-this gives us 30 into 200 again, which starts the whole thing all over. The answer, then, is 6.66666…, which equals 6 and 2/3.

Yes. We can use division to solve this. Since all percentages are based off 100%, we need to get 32/200 to a number over 100 (how percentages are formed). 32/200 - To get this to 100 we can see both numbers can be divided by 2. (32/2)/(200/2) = 16/100. 16% is the same as 16/100. So therefore 16% is equivalent to 32/200.
