To solve this problem, let's break it down:

- You have a mixture that is 75% milk in 300 ml. So, the milk volume is 0.75 * 300 = 225 ml.

- We want the mixture to become 45% milk.

- Let x be the amount of water in ml to be added.

- The total volume of the new mixture will be (300 + x) ml.

- The equation for 45% milk of the new mixture is:

\frac{225}{300 + x} = 0.45

- Solving the equation:

- 225 = 0.45(300 + x)

- 225 = 135 + 0.45x

- 90 = 0.45x

- x = 200
