Using PROPORTIONS to determine the unknown<br />
scale of an enlarged or reduced image from an<br />
original image with a known scale<br />
ORIGINAL IMAGE<br />
Scale 1 : 296,000<br />
(Step 1) Set up equivalence between original and reduced<br />
images<br />
(12.5 cm) x (296,000) = (7 cm) X (unknown scale)<br />
(Step 2) Solve for the unknown scale<br />
(unknown scale = (12.5 cm X 296,000) / (7 cm)<br />
(Step 3) Solve for the unknown scale<br />
unknown scale = 528,571<br />
(Step 4) The non-dimensional scale of the reduced image is ...<br />
1 : 528,571<br />
(Step 5) Is the computed scale logical YES<br />

NOTE: measurements in this sample calculation will not match those from your printout due the size of paper you’ve printed, or automatic<br />
shrinking/stretching accomplished by your software and/or printer. Original was 11x17. Presentation is 8-1/2x11.<br />
