Question

In a scale drawing of a house, 2 inches : 5 feet. The actual kitchen of the house will be 17 feet long. How long will the drawing of the kitchen be?

A. 5.2

B. 6.8

C. 7.5

D. 8

Answer 1

B, 6.8

Explanation:

Let's first find how many feet it is per 1 inch. We can do this by dividing 5 by 2

5/2= 2.5

Now it is 1 inch : 2.5 feet

17/2.5 = 6.8

1 x 6.8 = 6.8

6.8 inches : 17 feet

You could also solve this by doing

17/5 =3.4

3.4 x 2 = 6.8

6.8 inches : 17 feet
