Degrees and minutes are units to measure angles, as you know (or must know).


61 2/3°  is 61 whole degrees PLUS 2/3 of a degree.


One degree is 60 minutes.        (BY THE DEFINITION)


Hence, 2/3° is the angle of  %282%2F3%29%2A60 minutes = 40 minutes.


Thus  61 2/3° = 61°40', or, equivalently, in wording form,  61 degrees and 40 minutes.


The notion  " 40' " means 40 minutes.
