The total time Ali spent hiking and resting is 4 1/2 hours
How to add fractions
- Time spent hiking = 3 3/4hours
- Time spent resting = 3/4 hour
Total time spent hiking and resting = 3 3/4 + 3/4
= 15/4 + 3/4
= (15+3) / 4
= 18/4
= 9/2 hours
= 4 1/2 hours
Therefore, the total time Ali spent hiking and resting is four and one half hours (4 1/2) hours.
