Think About the Process The scale for the drawing of a rectangular
playing field is 2 inches = 3 feet. Find an equation you can use to find the
dimensions of the actual field. What are the actual dimensions?
width
6 in.
length
12 in
Find an equation you can use to find the dimensions of the actual field.
Use the equation y= x, where x is a dimension of the scale drawing (in inches) and y is the
corresponding dimension of the actual field (in feet).

y=x/2*3

Or, in LaTex, $y = \frac {x}{2} \cdot 3$

If you do this the regular way, you can see that there are three groups of 2 inches in the widths and six groups of 2 inches in the length(dividing by 2 inches and taking the unit out). Multiplying the number of groups by 3 feet, you get 9 feet as the width and 18 feet as the length, which makes sense since the drawing was at a 1:2 ratio for width to length.

But if you make this into an equation, consider the steps;

1) Divide by 2 (inches)

2) Multiply by 3 (feet)

And that's about it. So your equation would be;

y=x/2*3
