Hello from MrBillDoesMath!
Answer: Yes, (8 1/2) /`17 = ( 17 11/12) /23
** I think you meant 11 1/2 is to 23 NOT 17 11 1/2 is to 23"
Discussion:
First, 8 1/2 = 17/2 and
(17/2 ) / 17 = 1/2
Second 11 1/2 = 23/2 and
(23/2)/ 23 = 1/2
IN other words, the ratiors are the same:
8 1/2 11 1/2
------- = -------
17 23
Thank you,
MrB
