Question

There are 32 ounces of water in a glass.Someone drinks 55% of the water. How many ounces of water is left

Answer 1

55% of 32 ounces is 17.6. this means 32-17.6=14.4 ounces left

Answer 2

First, count how much is 55% from 32 ounces:

32 ounces - 100%

x ounces - 55%.

Mathematically you can write proportion:

`(32)/(x)=(100)/(55) ,\\ \\ x=(32\cdot 55)/(100) =17.6.`

Then you know that 17.6 ounces was drunk and you can calculate how much water left:

32-17.6=14.4

Answer: left 14.4 ounces of water.
