If 4.5 inches on a map convers 270 miles, what is the scale of inches to miles?
Answered by Ms. Sue
4.5/270 = 1/x

Cross multiply and solve for x.

Thanks so much

45 inches/2700 miles = .01666.....inch/mile

or 5 inches/300 miles

or
1 inch / 6 miles :)

Damon -- I think you overlooked the decimal point. It's 4.5 inches = 270 miles.
Answered by Damon
That is why I wrote 45 not 4.5 and 2700
Answered by Damon
easier to factor top and bottom that way
