Here’s your shmoop du jour, brought to you by Positive Integers.

00:06

The integers that aren’t always griping about Mondays.

00:13

If a, b, and c are positive integers, and a is greater than b, which is greater than c…

00:20

…which ratio must be the smallest… of the answer choices provided?

00:24

And here are the potential answers…

00:28

This problem can be solved in a number of ways,

00:30

but the easiest way is probably by elimination from the answer choices given.

00:34

Since we know that a is greater than b and b is greater than c,

00:38

we know that answer choices (A), (B), and (C) would all be larger than 1…

00:43

…since the larger numbers would all be on top of smaller numbers.

00:47

Option (D), on the other hand, is smaller than 1…

00:54

…so it's the smallest possible ratio… and the correct answer.

00:58

Our answer's D.
