Answer 1

If each story is 15 ft high, and there are 4 stories, how tall is the building in feet?

Answer 2

60 feet.

Answer 3

you'll need to convert units to work equal.
Then you make a simple rule:
if 5 inchs on paper represents x inches on building
then 1 inch on paper would mean x inches on the building

bear in mind that you'll need the complete height of the building.

Answer 4

1 feet is equal to 12 inches

Answer 5

thank you bruh.

Answer 7

Ok. You are correct.
The building is 60 ft tall.
In the scale drawing, the building is 5 inches tall.
We need the same units.
60 ft is how many inches?

Answer 8

720

Answer 9

Correct.
The scale is

drawing real
5 inches = 720 inches

The scale of a map or drawing is a ratio.
This ratio can be written as

\(\dfrac{5}{720} \)

Can you reduce the fraction?
