How do you make a 1 percent solution from a 10 percent solution?
You would need to add water. The amount required is entirely dependent on how much volume you currently have. If the current volume is x then the question can be rewritten as: 10%x/(x+a) = 1% where a is the amount of water you need to add. Multiply both sides by x+a and you get 10%x = 1%x + 1%a Subtract 1%x from both sides and get 9%x = 1%a Divide by 1% and you get 9x = a Thus, to make a 1 percent solution from a 10 percent solution, you need to add 9 times the current volume of the solution in water.
