Question

If on a scale drawing 15 ft are represented by 10 in then a scale of 1/10 in represents how many ft

Answer 1

Let be "x" the length in feet represented by a scale drawing of:

`(1)/(10)in`

You can write the given fraction as a Decimal number. To do this, you only need to divide the numerator by the denominator. Then:

`(1)/(10)in=0.1in`

Based on the information given in the exercise, you can set up the following proportion:

`(15)/(10)=(x)/(0.1)`

Now you must solve for "x" in order to find its value. This is:

`\begin{gathered} (0.1)((15)/(10))=x \\ \\ (1.5)/(10)=x \\ \\ x=0.15 \end{gathered}`

The answer is:

`0.15ft`
