Question

on a drawing, a scale of one half 1/2\=1 is given. a line on the drawing is \ long. what actual dimension does this 3\ line represent?

Explanation:

Step1: Set up proportion

Let \(x\) be the actual dimension. The proportion is \(\frac{1/2}{1}=\frac{3}{x}\).

Step2: Cross - multiply

\(\frac{1}{2}x = 3\times1\).

Step3: Solve for \(x\)

\(x=3\times2 = 6\).
