Question 697295
The other tutor's answer is wrong, because, for example

suppose a = 4.5   and   b = 8

4 < a < 7 < b < 9 because 4 < 4.5 < 7 < 8 < 9

However

a/b = 4.5/8 = .5625

and

4/7 = 0.5714 (rounded to 4 decimal places) 

and so 4/7 is GREATER THAN a/b, not LESS THAN a/b!!!

I'll show you how to do it later.
