Question

You want to make a new map with a scale of 1 in. = 35 mi. Two cities that are actually 175 miles apart, what would be the distance in inches between the cities on the new map?

Answer 1

You can do this with A. proportions, or B. with the factor-label method.

A.

1 in x in

_____ = ______ Cross multiply and get x = 5

35 mi 175 mi

B.

175 mi X 1 in/35 mi = 5 in, since the mi units cancel just like variables or constants. I recommend when using this method, using a horizontal line between numerator and denominator, which will be top and bottom, instead of /, which is less clear.
