Answer:
D. [tex]\frac{10}{15}[/tex] and [tex]\frac{14}{21}[/tex]
Step-by-step explanation:
Proportional ratios are ratios that represent the same relationship. One way to check this is to reduce the ratios, because if they are proportional, they will equal the same thing. Both [tex]\frac{10}{15}[/tex] and [tex]\frac{14}{21}[/tex] simplify to [tex]\frac{2}{3}[/tex].
Hope this helps!!
