A group of campers hiked for 5 3/4 hours today and 6 3/4 hours yesterday. How many hours did they hike in all?

Answers

Answer 1
Answer: First you can turn the fractions into improper fractions.
5 3/4 = 23/4    6 3/4= 27/4 
Add numerators, denominators stay the same.
23 + 27= 50
50/4
You can either leave it or simplify
Simplified:
50/4 = 12 1/2

Answer 2
Answer:

Final answer:

The campers hiked for a total of 12 1/2 hours. This was calculated by adding the whole numbers and the fractions separately and then combining the results.

Explanation:

This problem is an example of addition of fractions. To find the total number of hours that the campers hiked, we add the hours for both days. They hiked for 5 3/4 hours today and 6 3/4 hours yesterday. We add these together by firstly adding the whole numbers together, 5+6 equals 11. Then, add the fraction part, 3/4 + 3/4, which is 1 1/2. Combining the whole numbers with the fraction's sums to 12 1/2 hours. Thus, the campers hiked for 12 hours and 30 minutes in total.
