Question

Andrew spent 1 1/6 hours studying for his science exam. He spent another 1 1/2 hours on his history exam. How many total hours did Andrew spend studying for his exams?

Answer 1

1/6 of an hour is 60 minutes divided by 6 which is 10 minutes

1/2 of an hour is 30 minutes

Combine 1 hour and 10 minutes and 1 hour and 30 minutes and you get 2 hours and 40 minutes.
