Question 7) A container is 1/3 full of water and 1/4 full of oil. What fraction of the container is empưy?
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] Log in to Reply
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]
