Answer 1

Answer:

Seth watched TV for 6 3/4 hours last week.

Step-by-step explanation:

Let x be the number of hours he watched TV last week.

(2/3)x = 4 1/2 hrs.  Solve for x by mult. both sides by (3/2):

(3/2)(2/3)x = (3/2)(9/2)

Then:     x = 27/4 hours, or 6 3/4 hours.

Seth watched TV for 6 3/4 hours last week.
