Answer:
Ratio: 1:5 salt to water
Percentage of salt: 1/6 or 16.666.....
Explanation:
5 : 25 is the initial ratio, but we can simplify this down to 1:5 by dividing both sides by 5.
As for the percentage, in the 1:5 ratio you have 6 parts, 5+1. So the fraction would be 1/6 which is equal to 16.666 repeating.
Hope that helps!
