$\frac{9 dollars}{12 cans}=\frac{18 dollars}{24 cans}$

Work Step by Step

1. We are given that 9 dollars is to 12 cans as 18 dollars is to 24 cans. In order to write this as a proportion, we can write both relations as fractions. 9 dollars is to 12 cans can be written as $\frac{9 dollars}{12 cans}$ 18 dollars is to 24 cans can be written as $\frac{18 dollars}{24 cans}$ Next, we can set both fractions equal to each other, which gives us a proportional relationship. $\frac{9 dollars}{12 cans}=\frac{18 dollars}{24 cans}$ Since the units in the numerators and denominators are different, we do not simplify any further.
