Question

First answer gets brainalist On a scale model of a building, 14 inch represents 38 foot. What length on the model represents 1 foot?

​ 1. 3 3/2 ​ in.

​ 2. 2/3 ​ in.

3.​ 1 1/1 ​ in.

​​ 4.​ 10 2/3 ​ in.

Answer 1

7/19 in.

Explanation:

Use a proportion. Let x equal the unknown model length.

model/real = (14 in.)/(38 ft) = x/(1 ft)

(14 in.)/(38 ft) = x/(1 ft)

Cross multiply.

38 ft * x = 1 ft * 14 in.

Divide both sides by ft.

38x = 14 in.

Divide both sides by 38.

x = (14 in.)/(38)

x = 7/19 in.
