Scale = 1.5

Step-by-step explanation:

Given

Printer = (4.5',3')

Keogh = (3',2')

Required

Determine the scale

This is calculated as:

$Scale = \frac{Original}{Actual}$

$Scale = \frac{(4.5,3)}{(3,2)}$

Factorize the numerator

$Scale = \frac{1.5 * (3,2)}{(3,2)}$

Scale = \frac{1.5 * (3,2)}{(3,2)} $Scale = 1.5 * \frac{(3,2)}{(3,2)}$

Scale = 1.5 * 1

Scale = 1.5
