To determine if the ratios 4.21.5 and 12.6 4.5 are proportional, we first simplify them. The first ratio can be expressed as ( \frac{4.21}{5} ) and the second as ( \frac{12.6}{4.5} ). Calculating both gives ( \frac{4.21}{5} = 0.842 ) and ( \frac{12.6}{4.5} = 2.8 ). Since these two values are not equal, the ratios are not proportional.
