Mona had some free time, so she decided to go online and read about her favorite hobbies. She spent \( 14 / 15 \) of an hour on cooking, \( 7 / 15 \) of an hour on knitting, and \( 4 / 15 \) of an hour on baking. In addition, she spent \( 2 / 5 \) of an hour reading about dog training and \( 2 / 3 \) of an hour learning about sewing. In all, how many hours did Mona spend reading up on her hobbies?

To find out how many hours Mona spent on her hobbies, we need to add all the fractions of time she spent on each activity. 1. Cooking: \( \frac{14}{15} \) 2. Knitting: \( \frac{7}{15} \) 3. Baking: \( \frac{4}{15} \) 4. Dog Training: \( \frac{2}{5} \), which can be converted to a fraction with a denominator of 15: \( \frac{2}{5} = \frac{6}{15} \) 5. Sewing: \( \frac{2}{3} \), which can also be converted: \( \frac{2}{3} = \frac{10}{15} \) Now, we can add these fractions together: \[ \frac{14}{15} + \frac{7}{15} + \frac{4}{15} + \frac{6}{15} + \frac{10}{15} = \frac{41}{15} \] To convert \( \frac{41}{15} \) into hours, we can divide 41 by 15: \[ \frac{41}{15} = 2 \text{ hours and } \frac{11}{15} \text{ of an hour } \] Thus, Mona spent a total of 2 hours and 11/15 of an hour reading about her hobbies.
