This question is easily answered by subtracting two fractions. But it is easier if both fractions are in improper form.
5 3/4 is equal to 23/4
4 1/10 is equal to 41/10

difference = 41/10 - 24/4
difference = [ (2*41) - (5*24) ] / 20
difference = (82 - 120) / 20
difference = -38/20
difference = -19/10 or -1 9/10 less

If you would like to know how many more miles did Robyn run last week, you can calculate this using the following steps:

last week: 5 3/4 = 23/4 miles = 115/20 miles
this week: 4 1/10 = 41/10 miles = 82/20 miles

115/20 - 82/20 = (115 - 82) / 20 = 33/20 = 1 13/20 miles

The correct result would be 1 13/20 miles.
