Answer 1

B.
`(√(3))/(11), (\pi)/(24), (3)/(25), (9)/(100)`

Explanation:

The question is not properly presented. See attachment for proper presentation of question

From the attachment, we have that:

`W = (3)/(25)`

`X = (√(3))/(11)`

`Y = (9)/(100)`

`Z = (\pi)/(24)`

Required

Order from greatest to least

First, we need to simplify each of the given expression (in decimals)

`W = (3)/(25)`

`W = 0.12`

`X = (√(3))/(11)`

Take square root of 3

`X = (1.73205080757)/(11)`

`X = 0.15745916432`

`X = 0.16` --- approximated

`Y = (9)/(100)`

`Y = 0.09`

`Z = (\pi)/(24)`

Take π as 3.14

`Z = (3.14)/(24)`

`Z = 0.13083333333`

`Z = 0.13` --- approximated

List out the results, we have:

`W = 0.12`
`X = 0.16`
`Y = 0.09`
`Z = 0.13`

Order from greatest to least, we have:

`X = 0.16`
`Z = 0.13`
`W = 0.12`
`Y = 0.09`

Hence, the order of arrangement is:

`X = (√(3))/(11)`
`Z = (\pi)/(24)`
`W = (3)/(25)`
`Y = (9)/(100)`

i.e.

`(√(3))/(11), (\pi)/(24), (3)/(25), (9)/(100)`
