Answer 2

`4(3)/(4)` feet is the height of Ellen's sister.

Explanation:

Let the height of the sister of Ellen is = h feet

Ellen has the height =
`5(1)/(2)` feet

≈
`(11)/(2)` feet

Since her sister is
`(3)/(4)` foot shorter than Ellan.

So, h =
`(11)/(2)-(3)/(4)`

=
`(22-3)/(4)`

=
`(19)/(4)` feet.

=
`4(3)/(4)` feet

Therefore,
`4(3)/(4)` feet is the height of Ellen's sister.
