Answer 1

Answer:

$Empty = \frac{5}{12}$

Step-by-step explanation:

Given

$Water = \frac{1}{3}$

$Oil = \frac{1}{4}$

Required

The fraction that is empty

The constituent of the water can be represented as:

$Water + Oil + Empty = 1$

Make Empty the subject

$Empty = 1 - Water - Oil$

Substitute values for Water and Oil

$Empty = 1 - \frac{1}{3} - \frac{1}{4}$

Take LCM

$Empty = \frac{12 - 4 - 3}{12}$

$Empty = \frac{5}{12}$
