The ratio of red, white, and black in a solution is 3:5:7. This means that there are 3 parts of red, 5 parts of white, and 7 parts of black in the solution.
To calculate the percentage of white in the solution, we can use the following formula:
Percentage of white = (Number of parts of white / Total number of parts) * 100%
Substituting the given values, we get:
Percentage of white = (5 / 15) * 100%
Percentage of white = 33.33%
Therefore, the percentage of white in the solution is 33.33%.
So the answer is 33.33%
