# Quantitative Comparison Questions

## Description

Questions of this type ask you to compare two quantities — Quantity A and Quantity B — and then determine which of the following statements describes the comparison.

• Quantity A is greater.
• Quantity B is greater.
• The two quantities are equal.
• The relationship cannot be determined from the information given.

5. Simplify the comparison. If both quantities are algebraic or arithmetic expressions and you cannot easily see a relationship between them, you can try to simplify the comparison. Try a step-by-step simplification that is similar to the steps involved when you solve the equation for x,  or similar to the steps involved when you determine that the inequality is equivalent to the simpler inequality Begin by setting up a comparison involving the two quantities, as follows: where is a "placeholder" that could represent the relationship greater than (>), less than (<), or equal to (=) or could represent the fact that the relationship cannot be determined from the information given. Then try to simplify the comparison, step-by-step, until you can determine a relationship between simplified quantities. For example, you may conclude after the last step that represents equal to (=). Based on this conclusion, you may be able to compare Quantities A and B.
