Question

samuel measured a diner and made a scale drawing. the scale he used was 1 inch = 1 foot. what scale factor does the drawing use? simplify your answer and write it as a fraction.

Explanation:

Step1: Recall scale factor definition

Scale factor is drawing length over actual length. Here, drawing length is 1 inch, actual length is 1 foot. Convert feet to inches: 1 foot = 12 inches.

Step2: Calculate scale factor

Scale factor = $\frac{\text{drawing length}}{\text{actual length}}$ = $\frac{1\ \text{inch}}{12\ \text{inches}}$ = $\frac{1}{12}$.

Answer:

$\frac{1}{12}$
