You can put this solution on YOUR website! You need to get the daily mileage over a common denominator to add them.
You can do that by putting the full amount from each day in fractional form, or just adding the integer parts and then adding the fractional parts. Let's add the two parts separately
11 and 1/12 miles
You can put this solution on YOUR website! Convert mixed numbers into fractions:
5&1/3=16/3
2&1/4=9/4
3&1/2=7/2
Let's determine what the least common denominator would be. Upon visual inspection I pick 12.
Make the appropriate modifications to the fraction without changing the ratio
(16/3)(4/4)=64/12
(9/4)(3/3)=27/12
(7/2)(6/6)=42/12
Now add each fraction together to get the # of miles run during the week
(64+27+42)/12=11 and 1/12 miles
