On a map 1/2 of an inch represents 4/5 of a mile. what distance on the map represents 1 mile?

Since it is given that 4/5 mile is equal to 1/2 inch, what we will be looking for how many inches will there be for 1 mile. 5/5 mile = 1 mile. 

This is how it would look like.

1/2 inch       x inch

          =       

..4/5 mile 1 mile 

Next, we cross multiply:

(1/2)1 = (4/5)x

Then divide both sides by 4/5. so we get

x = 0.025 inch

and that is 1/40 inch. Therefore, 1 mile is 1/40 inch. Hope this helps.
