Question

Connie ran 5/6 of a mile on Saturday and 1 1/4 of a mile on Sunday . If she wants to run a total of 3 miles before Tuesday , how far does she need to run on Monday

Answer 1

Connie ran 5/6 of a mile on Saturday and 1 1/4 of a mile on Sunday.

$\frac{5}{6} + 1 \frac{1}{4} \\ = \frac{5}{6} + \frac{5}{4} \\ = \frac{10 + 15}{12} \\ = \frac{25}{12} = 2 \frac{1}{12} \: km$

If she wants to run a total of 3 miles before Tuesday , she need to run on Monday

$3 - \frac{25}{12} \\ = \frac{36 - 25}{12} \\ = \frac{11}{12} \: km$
