Can someone explain the top question please? Thanks!

x-1, x, 1-x, -1÷x

Step-by-step explanation:

Ok so what your going to do is plug in 1/4 for x for each of those equations.

For example, the 2nd number is 1-x. You would make x 1/4.

It would be 1- 1/4 which would be 3/4

the 3rd would be 1/4-1 which would be -3/4

1st one is 1/4

last one is -1/ 1/4 which is 4

1.1/4

2.3/4

3.-3/4

4.4

List from least to greatest.
