Answer:
1/3 or 0.33 feet
Step-by-step explanation:
This question can be easily answered by using simple proportions.
If 75 feet are represented by 45 inches on a scale, then the scaling factor from feet to inches is 45/75, or from inches to feet is 75/45
If we have 1/5 inch and want feet, just multiply by 75/45 to get
1/5*75/45=1/3=0.33 feet
Answer:
1/3 feet
Step-by-step explanation:
We are given that
On a scale drawing
45 inches represented =75 feet
We have to find a scale of 1/5 inch how many feet represents.
To find the value in feet represented by a scale of 1/5 inch we will use unitary method.
Using unitary method
45 inches represents =75 feet
1 inch represents =[tex]\frac{75}{45}[/tex] feet
1/5 inch represents =[tex]\frac{75}{45}\times \frac{1}{5}[/tex] feet
1/5 inch represents=[tex]\frac{1}{3}[/tex] feet
Hence, a scale of 1/5 inch represents 1/3 feet
