1. Question 1

   Which of the following ratios is the greatest?

   1. A. 2 : 3
   2. B. 5 : 8
   3. C. 3 : 4
   4. D. 7 : 12
   Answer and explanation

   ✓ Correct answer: C. 3 : 4

   Write the ratios as fractions over the common denominator 24: 2/3 = 16/24, 3/4 = 18/24, 5/8 = 15/24, 7/12 = 14/24; so 3 : 4 is the greatest.

   A ratio compares two quantities of what kind?

   1. A. Quantities of the same kind
   2. B. Quantities of different kinds
   3. C. Lengths only
   4. D. Fractions only

   ✓ Correct answer: A. Quantities of the same kind

   A ratio compares two quantities of the same kind by saying how many times one is of the other; comparing quantities of different kinds is meaningless.
