Chapter 6.6, Problem 28E

To determine

To find : The scales without unit.

Answer to Problem 28E

Thescales without unit is $1:360$

Explanation of Solution

Given information:

Consider the scale with units, 1in. : 10 yd.

Calculation :

The scale with units is 1in. : 10 yd.

1yd = 36in.

Therefore,

10yd = $36\times 10$ in.

  $10\text{ yd }=360\text{ in}\text{.}$

Therefore,

scale without unit is,

  $\begin{array}{l}\frac{1\text{ in}\text{.}}{10\text{ yd}}\\ =\frac{1\text{ in}.}{360\text{ in}.}\\ =\frac{1}{360}\\ =1:360\end{array}$

And scale without unit will be $1:360$
