sadie has a cousin nanette in germany. both families recently bought new cars and the two girls are comparing how fuel efficient the two cars are. sadie tells nanette that her family’s car is getting 42 miles per gallon. nanette has no idea how that compares to her family’s car because in germany mileage is measured differently. she tells sadie that her family’s car uses 6 liters per 100 km. which car is more fuel efficient?
(1 mile = 1.609 km and 1 gallon = 3.79 liters)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
