Answer
$11, \sqrt {14}, \frac{5}{2}, 1, -\frac{9}{16}$
Work Step by Step
$11$ is the largest of the five numbers.
$\sqrt {14}$ is equal to about $3.74$.
$\frac{5}{2}$ is $2.5$.
The number 1 would be the second to the lowest number.
$-\frac{9}{16}$ is $-0.5625$, which is the lowest of the five numbers.
So the order of the five numbers in descending order is:
$11, \sqrt {14}, \frac{5}{2}, 1, -\frac{9}{16}$
