Hi Rosaline, if Fred runs 1 and 1 / 4 miles in the first 15 minutes and 1 and 3 / 8 in the last 15 minutes, to find the total miles run, add the value of the first 15 minutes to the value of the last 15 minutes.
Total miles = 1 1 / 4 + 1 3 / 8
Convert both values to 8ths:
1 1 / 4 = 5 / 4 = 10 / 8
1 3 / 8 = 11 / 8
Total miles = 10 / 8 + 11 / 8, or 21 / 8, or 2 and 5 / 8 miles.
Fred ran a total of 2 and 5 / 8 miles.
