Anita can clean 1/8 portion of the pool in 1 hour
Chao can clean 1/6 portion of the pool in 1 hour
Both of them working together can clean 1/8 + 1/6 = 7/24 portion of the pool in 1 hour
Therefore, it will take both of the working together 1/(7/24) = 24/7 or 3 3/7 hours to clean a typical pool.
Answer:
3. 3:5
4. 4:1
Step-by-step explanation:
Just ratios I believe, myb if it's wrong but that should be it.
Since 3 & 5 aren't divisible by anything the scale factor is just 3:5.
Since 24 & 6 are divisible by a common number, being 6, you'd divide 24:6 & get a scale factor of 4:1.
