Question

jake drew a scale drawing of a house. he used the scale 1 inch = 1 foot. what is the scale factor of the drawing? simplify your answer and write it as a fraction.

Explanation:

Step1: Convert units to same system

We know that 1 foot = 12 inches. The scale is 1 inch (drawing) to 1 foot (actual), so we convert 1 foot to inches.

Step2: Find scale factor as fraction

The scale factor is the ratio of drawing length to actual length. So it's $\frac{1\ \text{inch}}{12\ \text{inches}}=\frac{1}{12}$.

Answer:

$\frac{1}{12}$
