Answer:
Matt ran 6 miles.
Step-by-step explanation:
Stan ran 4 and 7/10 miles, and this is 1 and 3/10 fewer miles than Matt.
this means that Matt ran the following amount of miles
4 and 7/|0 + 1 and 3/10 miles:
(4 + 1) + (7/10 + 3/10) = 5 + 10/10 = 6 miles.
This would be the correct way to solve this equation.
