Show answer & explanation
Correct answer: B
Concept
A ratio compares two quantities in a fixed order. To simplify a ratio, divide both terms by their greatest common divisor; the order of the quantities must remain unchanged.
Application
From the LCD row of the table, production in 2008 is 9,000 and production in 2010 is 12,000.
Write the required ratio in the stated order: 9,000 : 12,000.
The greatest common divisor of 9,000 and 12,000 is 3,000. Dividing both terms by 3,000 gives 3 : 4.
Cross-check
Multiplying 3 : 4 by 3,000 reproduces 9,000 : 12,000, so the simplified ratio is 3 : 4.
Result
Therefore, the ratio of LCD production in 2008 to LCD production in 2010 is 3 : 4.
