Answer:
[tex]Empty = \frac{5}{12}[/tex]
Step-by-step explanation:
Given
[tex]Water = \frac{1}{3}[/tex]
[tex]Oil = \frac{1}{4}[/tex]
Required
The fraction that is empty
The constituent of the water can be represented as:
[tex]Water + Oil + Empty = 1[/tex]
Make Empty the subject
[tex]Empty = 1 - Water - Oil[/tex]
Substitute values for Water and Oil
[tex]Empty = 1 - \frac{1}{3} - \frac{1}{4}[/tex]
Take LCM
[tex]Empty = \frac{12 - 4 - 3}{12}[/tex]
[tex]Empty = \frac{5}{12}[/tex]
