This is simple math to dilute a liquid calculation of percentage, liquid like.., alcohol, Hydrogen Peroxide, Sodium hydrochloride or any type of liquid with its solvent/water. in this case dilute 35% H2O2 with water to reach 5% of hydrogen peroxide.
Example 2: Dilute 95% alcohol to 75% then..
(95/75)-1 then the ratio is 1: 0.26667
means 1 cup alcohol with a empty cup (26.667% filled) water , mix to get 75% diluted alcohol .
