Answer 2

Thanks so much

Answer 3

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

or 5 inches/300 miles

or
1 inch / 6 miles :)

Answer 4

Damon -- I think you overlooked the decimal point. It's 4.5 inches = 270 miles.

Answer 5

That is why I wrote 45 not 4.5 and 2700

Answer 6

easier to factor top and bottom that way
