Question

The distance from your home to the local library is 5 1/4 miles. You are making a scale drawing of your neighborhood. How many inches need to be draw to represent the distance to the library using the scale of 1 inch=3 miles?

Answer 1

A scale is a ratio, a ratio is a fraction and ratios are maintained so...
1inch=3miles But this is a ratio, that means that.
inch/miles will be maintained.
\[\frac{inches}{miles}=\frac{1}{3}=\frac{x}{5.25}\]
So you can solve this:
\[\frac{1}{3}=\frac{x}{5.25}\]
And you've got your answer.
