Daria's goals is to run 7 miles each weekend. she ran 3 1/3 miles on Saturday and 3 3/4 miles on Sunday. By how much did she beat her goal

You add using the common denominator, 3 3/4 and 3 1/3 then you should get 7 1/12, to find the total miles. she ran 7 and 1/12th miles, so she ran a 12th mile over her goal.

She beat her goal by 1/12 of a mile.

3+3=6

1/3 multiply both numbers by 12. that gives you 4/12

3/4 multiply both numbers by 12. that gives you 9/12

add the numerators together. that gives you 13/12

12/12=1, so 13/12 = 1 1/12
