You could set up a ratio given that it is a 5% solution (5% of the total, not 5% of water.
5/100 = x/473 You need to find out how much is vinegar. Cross multiply
5 * 473 = 100 x Find the number on the left.
2365 = 100 x Divide by 100
2365 / 100 = x
x = 23.65 mL of vinegar.
The water is found by subtraction
473 - 23.65 = 449.35 mL of water.
