determine if there is a proportional relationship between the two quantities. explain your reasoning.
1) a b
35 92
23 80
2) c d
20 8
12.5 5
- the answer for 1) a and b is a and b are not proportional. the ratios of the values of a to b are not equal.
- the answer for 2) c and d are proportional. the ratios of the values of c to d are equal.
just explain how to know how to determine its proportional and not proportional.
