A ratio is a type of fraction.
If you change everything to minutes, then you get 13minutes/ 30 minutes.
However, the problem wants the answer in minutes to hours.
1. Write your answer as a fraction: 130 minutes/5 hours.
2. Write in lowest terms by dividing the top number (numerator) and the bottom number by 5.
130÷5 = 26 minutes/1hour
3. In a story problem, this would mean that something is happening for 26 minutes during a one hour period. For example, maybe, someone reads for 26 minutes out of every hour.
