How much water should be added to 1 gallon of pure antifreeze to obtain a solution that is 35% antifreeze? to obtain a 35% antifreeze solution, □ gallon(s) of water should be added(simplify your answer.)

1.9 gallon

Step-by-step explanation:

Let 'x' be the amount of water that needed to be added to 1 gallon of pure antifreeze to obtain a solution that is 35% antifreeze.

Total mass of solution = 1+x

Ratio of amount of antifreeze to the total solution :

Ratio of value of antifreeze to the total solution :

The proportion of the amount of antifreeze to the total solution will be :

Hence, the amount of water that is needed to be added =1.9 gallon
