Answer :
We need to find a common denominator and it'll be pretty clear.
16 6/9 ?= 16 16/18
The common denominator is 18 (18 = 9 * 2), so we multiply both 6 and 9 by 2.
16 12/18 < 16 16/18
16 6/9 ?= 16 16/18
The common denominator is 18 (18 = 9 * 2), so we multiply both 6 and 9 by 2.
16 12/18 < 16 16/18
