Brian is walking 2 3/4 of a mile everyday. He does this for one week.

1. Express the distance that Brian walks each day as a improper fraction.

2. What is the total distance Brian walks for the week? Express your answer as a mixed number.

1. 11/4

2. 19 1/4

Step-by-step explanation:

To change into an improper fraction:

((2 times 4)+3)/4

=11/4

To calculate total distance:

(11/4) times 7

=77/4

=19 1/4
