Answer:
Amount of chemical solution = 18 gallon
Amount of pure water = 22 gallon
Step-by-step explanation:
Assume;
20% of solution = x
So,
Amount of pure water = 40 gallons - x
Amount of pure water = 40 - x
Computation:
20% of x = 9% of 40 gallon
0.2 x = 3.6
x = 3.6 / 0.2
x = 18 gallon
So,
Amount of chemical solution = 18 gallon
Amount of pure water = Total solution - Amount of chemical solution
Amount of pure water = 40 -18
Amount of pure water = 22 gallon
You have to multiply 1/4 by 2 to get the same reciprocal as the other fraction and then you’ll subtract 2/8 to both sides which would leave you with w> 5/8
