Question

peter drew a scale drawing of a restaurant. the scale of the drawing was 9 inches : 5 feet. a table in the restaurant is 10 feet long in real life. how long is the table in the drawing?
inches

Explanation:

Step1: Understand the scale

The scale is 9 inches : 5 feet, which means 5 feet in real life corresponds to 9 inches in the drawing.

Step2: Find the ratio of inches to feet

First, find how many inches correspond to 1 foot. Let \( x \) be the inches per foot. We have the proportion \(\frac{9}{5}=x\), so \( x = \frac{9}{5} \) inches per foot.

Step3: Calculate the length in the drawing

The real length is 10 feet. So the length in the drawing is \( 10\times\frac{9}{5} \).
\( 10\times\frac{9}{5}=\frac{90}{5} = 18 \)

Answer:

18
