A drawing of a room has a scale of 1/4 inch = 1 foot
. Which choice DOES NOT represent a proportional relationship, according to the scale?
1 1/2
inch drawing, 6 feet actual
1 and 1 half inch drawing, 6 feet actual
1 inch drawing, 3 feet actual
1 inch drawing, 3 feet actual
2 inch drawing, 8 feet actual
2 inch drawing, 8 feet actual
1/2
inch drawing, 2 feet actual
1/2 inch drawing, 2 feet actual
how did you come to that??
I apologize for the mistake in my response. Let's work through this together:
Given scale: 1/4 inch = 1 foot
1 1/2 inch drawing, 6 feet actual:
1.5 inches x (1 foot / 1/4 inch) = 6 feet
This is a proportional relationship since both sides are equal.
1 inch drawing, 3 feet actual:
1 inch x (1 foot / 1/4 inch) = 4 feet
This is also a proportional relationship.
2 inch drawing, 8 feet actual:
2 inches x (1 foot / 1/4 inch) = 8 feet
This is a proportional relationship.
1/2 inch drawing, 2 feet actual:
1/2 inch x (1 foot / 1/4 inch) = 2 feet
This is a proportional relationship.
Therefore, all the choices represent proportional relationships according to the scale given. Apologies for the confusion in my initial response.
