Worked practice questions

A bowl holds 8 oranges and 6 lemons. What is the ratio of oranges to lemons in simplest form?

  1. 4:3
  2. 3:4
  3. 8:14
  4. 4:7
Show answer and solution

Correct answer: A. 4:3

1. Write the ratio of oranges to lemons as 8:6. 2. Divide both terms by their common factor 2 to get 4:3. 3. 3:4 reverses the order, and 8:14 and 4:7 compare oranges with the total fruit. _Source: Wikipedia, Ratio, lead section_

What do we call a statement that two ratios are equal?

  1. A rate
  2. A proportion
  3. An index
  4. A fraction
Show answer and solution

Correct answer: B. A proportion

1. A ratio compares two quantities. 2. When two such ratios are said to be equal, for example 6:8 and 3:4, the statement is a proportion. 3. A rate compares different units and an index is a single measure, so neither fits. _Source: Wikipedia, Ratio, lead section_

In the ratio A:B, the first term A is called the

  1. consequent
  2. extreme
  3. mean
  4. antecedent
Show answer and solution

Correct answer: D. antecedent

1. The two numbers in a ratio are its terms. 2. The first term is the antecedent and the second term is the consequent. 3. Extremes and means belong to a proportion of four terms, not to a single ratio. _Source: Wikipedia, Ratio, Notation and terminology_
