Hmm... tricky one... 200 !
20
220 is 200 increased by one tenth of 200 200.1 is 200 increased by one tenth.
It is: 1/10 of 2000 = 200
It is: 1/4*1/10*1/5*200 = 1
25% of 10% of 200 really says," One quarter of one tenth of 200?" Well, one tenth of 200 is 20, and a quarter of that is 5. It is equally correct to find the 1/4 of 200 first. That's 50, and then find 1/10 of that = 5. The same answer.
200 / 10 = 20
