Answer :
Saturday: ran 4 1/2 miles
Sunday: ran 7 1/3 miles
4 1/2 + 7 1/3
4 3/6 + 7 2/6= 11 5/6
Tim ran 11 5/6 miles total
Sunday: ran 7 1/3 miles
4 1/2 + 7 1/3
4 3/6 + 7 2/6= 11 5/6
Tim ran 11 5/6 miles total
Saturday 4 1/2
Sunday 7 1/3
First you would have to find common denominator
4 1/2 + 7 1/3
4 3/6 + 7 2/6 = 11 5/6
So, Tim ran a total of 11 5/6 miles on both days.
Hope that helps you. :-)
