Question

Does this represent a proportional relationship? Explain your answer. A specific shade of orange paint calls for 2 parts yellow and 3 parts red. Catie uses 3 cups of yellow paint and 4 cups of red paint to make orange paint.

Answer 1

proportional relationship is not represented by them

Explanation:

Ratio a/b and c/d are said to be proportional if a/b = c/d.

_________________________________________________

ratio of yellow part and red part for specific shade of orange =

2 part yellow/ 3 parts red = 2/3

____________________________________________________

ratio of yellow part and red part used by Catie =

3 cups of yellow/ 4 cups of red = 3/4

______________________________________

we have two ratio 2/3 and 3/4

but 2/3 is not equal to 3/4

hence , proportional relationship is not represented by them.
