问题 If 8a=9b and ab≠0, what is the ratio of ?
选项 A、 
B、 
C、 
D、 
E、 
答案C
解析 The ratio of these numbers is (a/9)/(b/8); you can substitute in the ratios from the question, so a=9b/8; the ratio then is (9b/72)/(b/8); divide b from both sides of the ratio, and multiply 8 times both sides of the ratio, and you wind up with 72/72=1.
