To compare two similar quantities, their units must be same. Ned’s height is in cm and Ted’s height is in ft. In order to compare those heights, we need to convert both the heights to same units.
Thus, 4.5 ft=4.5×0.3 m=1.35 m
Now, 1m = 100 cm
Thus, 4.5 ft=1.35 m=1.35×100 cm=135 cm
Thus, Ned′s heightTed′s height=135135=1
