On a map, Julia's home is 8.5 in. from the library. If the map scale is 1 in.: 0.25 mi, how many miles from the library does Julia live?
If the map scale is 1 inch: 0.25 miles, then we can multiply 0.25 x 8.5 to get our answer. 0.25 x 8.5 = 2.125, so Julia's home is 2.125 miles away from the library. :)
