I'd set up a ratio problem

3/4 inch = 1 mile
----------- --------
1 3/4 inch x

3/4 x = 1 3/4
divide each side by 3/4 (also change 1 3/4 to improper)

you end up with
x = 7/4 x 4/3
x = 28/12
x = 7/3 or 2 1/3

hope this helps

Answer:

The distance is
(7)/(3) mile

Explanation:

Given : On a certain map,
(3)/(4) inch represents one mile.

To find : What distance, in miles, is represented by
1(3)/(4) inches?

Solution :

We have given that,

1 mile =
(3)/(4) inch

or 1 inch =
(1)/((3)/(4)) mile

1 inch =
{(4)/(3) mile

We have to find miles in
1(3)/(4) inches i.e.
(7)/(4) inches


(7)/(4) inch =
(7)/(4)* {(4)/(3) mile


(7)/(4) inch =
(7)/(3) mile

Therefore, The distance is
(7)/(3) mile
