Answer:

The ratio of Trucks to Cars is

3: 14

The ratio of Hot Dogs to Hamburgers is

3 : 5

Step-by-step explanation:

There are 42 cars and 9 trucks, and since they asked to write the ratio of trucks to cars, we write it as they asked. Therefore the ratio would be

9 : 42  \\ \\  \frac{9}{3} :  \frac{42}{3}  \\ \\   = 3 : 14

There are 24 hotdogs and 40 hamburgers, since they asked us to write the ratio of hotdogs to hamburgers we are going to write it as it was said. Therefore the ratio is

24 : 40 \\  \\  \frac{24}{8}  :  \frac{40}{8}  \\  \\  =  3 : 5
