A more intuitive solution would be a simple comparison.
3.5/7 is half. 4/7 is 0.5 extra in numerator.
4.5/9 is half. 5/9 is 0.5 extra in numerator. Since the numerator here is greater than previous, 0.5 is a smaller percentage extra. So 5/9 is closer to half than 4/7.
The same logic will be applicable for 6/11 and 7/13 too which makes 7/13 the smallest among them (but still greater than 1/2)
8/16 is half and 9/16 is 1 extra in numerator. So the extra is a greater percentage now than in the case of 7/13.
Hence 9/16 is greater than 7/13.
