A certain drink is made by adding 4 parts water to 2.5 part drink mix. What percent of the mixture is water? Omit % sign in your answer. Round your answer to the nearest tenth.

The mixture contains 61.5% of water.

Step-by-step explanation:

Total parts = 4 + 2.5 = 6.5

Parts of water = 4

parts of drink = 2.5

Percent of water in the mixture = 4 * 100 / 6.5

= 400/6.5

= 61.53%

It is rounded to the nearest tenth as 61.5%.
