Since Kirbe wants to run 7 5/8 miles in two days each week, we have to divide this quantity by 2. First lets convert it to an improper fraction:
[tex]7\frac{5}{8}=\frac{7\cdot8+5}{8}=\frac{56+5}{8}=\frac{61}{8}[/tex]dividing 61/8 by 2 we get:
[tex]\frac{\frac{61}{8}}{2}=\frac{61}{8\cdot2}=\frac{61}{16}=3\frac{13}{16}[/tex]therefore, Kirby must run 3 13/16 miles on Tuesdays and Thursday so we runs 7 5/8 miles ech week
