Question

How do you order the following from least to greatest `-sqrt5, pi/2, pi/3, 4 5/8, sqrt18`?

Answer 1

`-sqrt(5), pi/3, pi/2, sqrt(18), 4 5/8`

Explanation:

`-sqrt(5)` is the only negative number so it is the smallest.

`1/3 < 1/2`, so `pi = 3.14159...` will make `pi/3 ~~ 1` and `pi/2 ~~ 1.5`

`sqrt(18)` is close to `sqrt(16) = 4`, so `sqrt(18) ~~ 4.2`

`5/8 = 0.625`, so `4 5/8 = 4.625`
