James run 12 3/4 miles per day. He runs for 6 days the same amount of miles each day. How many miles does he run in all?
The number of miles run in all 6 days: 6 12 3/4
Change 12 3/4 to improper fraction = (124 + 3) / 4 = (48 + 3) / 4 = 51 / 4
6 51/4
3 51/2 = 153/2 = 76.5
Miles run in all = 76.5 Miles.
Hope this explains it.
The answer is: 76.5 mi. (or, write as: 76 ½ mi. ).

Explanation:
(12 ¾ mi / d) 6 d = ? mi.
__________________________
On the "left-hand side" of the equation, the units of "d" [for day(s)] cancel; and we are left with:
_________________
12 ¾ mi 6 = ? mi. ;
__________________________
12 ¾ mi 6 = (12 ¾ 6) mi. = 76.5 mi. (or, write as: 76 ½ mi. ).
