Question

mr sawicki made a scale drawing of a basketball court that has a scale of 1 inch = 3 yards. what is the length of the scale drawing? think about how many groups of 1 inch you need to represent 30 yards. there are 10 groups of 3 yards in 30 yards.

Explanation:

Step1: Identify the scale ratio

The scale is 1 inch = 3 yards.

Step2: Set up a proportion

Let $x$ be the length of the scale - drawing in inches. We know that $\frac{1\text{ inch}}{3\text{ yards}}=\frac{x\text{ inches}}{30\text{ yards}}$.

Step3: Solve the proportion

Cross - multiply: $3x = 30$. Then $x=\frac{30}{3}=10$.

Answer:

10
