Question

Heip Kirby plan some tuture weekly runs. How many miles could he run on Tuesdays anThursdays so that he runs 7 5/8 miles each week? List at least three possibilities below

Answer 1

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:

$7\frac{5}{8}=\frac{7\cdot8+5}{8}=\frac{56+5}{8}=\frac{61}{8}$

dividing 61/8 by 2 we get:

$\frac{\frac{61}{8}}{2}=\frac{61}{8\cdot2}=\frac{61}{16}=3\frac{13}{16}$

therefore, Kirby must run 3 13/16 miles on Tuesdays and Thursday so we runs 7 5/8 miles ech week
