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.

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
