Answer 1

1 and 1/8 hours or

Explanation:

Natasha spent one and a half hours on the beach, which can be rewritten as 3/2 hours. Out of that time, she spent 3/4 sleeping. The total time she spent sleeping on the beach is determined by the product of the amount of time she spent on the beach by the fraction of that time she spent asleep:

`T=(3)/(2) * (3)/(4)\\T=(9)/(8) \\T=1 + (1)/(8)`

Natasha was asleep on the beach for 1 and 1/8 hours or 1 hour 7 minutes and 30 seconds.
