In the ratio 08:27 :: ?:64, what number completes the pattern?
8 is the cube of 2 (2 cubed) and 27 is the cube of 3 (3 cubed) - consecutive cubes. Similarly, 64 is the cube of 4 (4 cubed), so the missing number should be the cube of 3, which is 27, keeping the same 'consecutive cubes' relationship.
Re-check your working by substituting the answer back into the original question.
