Read exercise and reference answers
Steps
  1. Name the two quantities that vary
  2. Ask what happens to the second when the first increases
  3. If it also increases, the proportion is direct
  4. If it decreases, the proportion is inverse
  5. Write the matching equation and solve
Type first, equation second, arithmetic last. Source: syllabus Maths, Ch 11 Direct and Inverse Proportions.

In mathematics, a ratio is used to:

  1. Add two quantities together
  2. Compare two quantities
  3. Find the average of two quantities
  4. Convert a quantity into a percentage
Show answer and solution

Correct answer: B. Compare two quantities

1. A ratio sets one quantity against another. 2. Ratio means comparing two quantities. 3. If a basket has 20 apples and 5 oranges, the ratio of oranges to apples is 5 : 20, read as 1 : 4. 4. The comparison can equally be written as a fraction, here one fourth. 5. Adding or averaging combines the quantities rather than comparing them. _Source: syllabus Maths, Ch 7 'Comparing Quantities', S7.1 Recalling Ratios and Percentages_
