Let's first find out how much of the job each person can do in one hour.
Anita can clean 1/8 of the pool in one hour, and Chao can clean 1/6 of the pool in one hour.
Working together, Anita and Chao can clean (1/8 + 1/6) of the pool in one hour.
To add these fractions, we need a common denominator, which in this case is 24.
1/8 = 3/24
1/6 = 4/24
Now we add them together:
3/24 + 4/24 = 7/24
Therefore, Anita and Chao working together can clean 7/24 of the pool in one hour.
To find out how long it will take them to clean the whole pool together, we need to invert this fraction:
1 / (7/24) = 24/7
So it will take Anita and Chao 24/7 hours to clean a typical pool working together. This can also be written as a mixed number, which is approximately 3 and 3/7 hours.
