Question

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?

Answer 1

The answer is: 76.5 mi. (or, write as: 76 ½ mi. ).
______________________
Step-by-step 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. ).

Answer 2

The number of miles run in all 6 days: 6 * 12 3/4

Change 12 3/4 to improper fraction = (12*4 + 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.
