-4 for the first one and 2/3 for the second
Answer:
38.5
Step-by-step explanation:
The equation for this would be 41/4 + 52/3 - 41/3= ?
So then you just change all the denominators to their lcm, which is 12 and multiply the numerator accordingly.
123/12 + 208/12 - 164/12 = 167/12
First pool: 21 liters per min so to get 3100 gone do 3100 divided by 21 which equals 147
Second pool: 33 liters per min and you have 3472 divided 33 = 105
