Answer:

Karma worked for 7 1/2 hours. She spent 2/3 of the time on her computer. To find out how long she was on her computer, we can multiply the total time she worked by the fraction of time she spent on her computer.

Explanation:

7 1/2 hours * 2/3 = (15/2) * (2/3) = 30/6 = 5 hours.

Therefore, Karma was on her computer for 5 hours.

Answer:

5

Explanation:

We want to multiply a mixed number by a fraction.

7 1/2 * 2/3

Change the mixed number to an improper fraction.

(2 * 7 + 1)/2 = 15/2

15/2 * 2/3

Simplify.

15/3 * 2/2

5 * 1

5
