Solution to Tanya's Homework Task

To find out how much time Tanya spent solving the problems, we can use the given information that she spent 4/5 of the total time on solving the problems.

Let's calculate the time Tanya spent solving the problems:

1. Calculate Total Time Spent: Tanya spent 1 1/2 hours on her homework. 2. Calculate Time Spent on Problem Solving: Tanya spent 4/5 of 1 1/2 hours on solving the problems.

Calculation

1. Total Time Spent: - 1 1/2 hours can be converted to an improper fraction as 3/2 hours. 2. Time Spent on Problem Solving: - 4/5 of 3/2 hours can be calculated as (4/5) * (3/2) hours.

Answer

Tanya spent 4/5 of an hour or 48 minutes solving the problems.
