Question

luna drew a scale drawing of the high school. the parking lot, which is 54 meters wide in real life, is 102 centimeters wide in the drawing. what scale did luna use? 17 centimeters : meters

Explanation:

Step1: Set up proportion

Let $x$ = real meters for 17 cm.
$$\frac{102\ \text{cm}}{54\ \text{m}} = \frac{17\ \text{cm}}{x\ \text{m}}$$

Step2: Solve for $x$

Cross-multiply: $102x = 54 \times 17$
Calculate right-hand side: $54 \times 17 = 918$
Isolate $x$: $x = \frac{918}{102}$

Step3: Simplify the value

$$x = 9$$

Answer:

9
