Julia studied math for 3 1/3 hours during the 4 days before her last math test. What was the average amount of time she studied each day?

For this question I got 38.6 but that's really off.

Can someone tell me how I got this wrong in words?

answer 13.33333 hours h

Step-by-step explanation:

Julia studied 3 1/3 hours during 4 days

this means she studied:

3 1/3 of 4 days of 24 hours

3 1/3 = 9/3 x 1/3 = 10/3

and 4 days of 24 hours is 4 x 24 = 96

there for

10/3 x 96 = (10/1) x32 = 320 hours

320/24 hours each day - 13.3333
