Question

1. if 1 inch = 2.54 cm, circle which proportion shows how many centimeters are equal to 15 inches?

\\( \frac { 2.54 } { 1 } = \frac { 15 } { x } \\) \\( \frac { 2.54 } { 1 } = \frac { x } { 15 } \\) \\( \frac { 2.54 } { 15 } = \frac { x } { 1 } \\) \\( \frac { 2.54 } { x } = \frac { 15 } { 1 } \\)

Explanation:

Step1: Set up proportion

Since 1 inch corresponds to 2.54 cm and we want to find \(x\) (cm) for 15 inches. The proportion should be \(\frac{2.54}{1}=\frac{x}{15}\) (ratio of cm to inches for both cases).

Answer:

\(\frac{2.54}{1}=\frac{x}{15}\)
