There are three fences on a ranch measure 15/16 miles 7/8 miles and 7/16 mile which is the best estimate of the total length of all three fences

Alright, lets get started.

The length of first fence =

The length of second fence =

The length of third fence =

Total length of all three fence =

For adding them, we need to first make common denominator

Total length of all three fence =

Total length of all three fence =

Now we have common denominator, so

Total length of all three fence =

Total length of all three fence =

36 and 16 could be simplified with 4, so

Total length of all three fence =   :    Answer

Hope it will help :)
