As we everybody know.. Loop back address is

127.0.0.0 (Entire network address)

Here -

First Octate - 127

Second Octate - 0

Third Octate - 0

Forth Octate - 0

Convert those in binary - Using (128 64 32 16 8 4 2 1) code....

First Octate - 0 1 1 1 1 1 1 1
Second Octate - 0 0 0 0 0 0 0 0
Thirde Octate - 0 0 0 0 0 0 0 0
Fourth Octate - 0 0 0 0 0 0 0 0

So binary add of loopback address -

01111111 00000000 00000000 00000000

Note:

0 : Zero designate the corresponding decimal code value zero.

1 : One designate the corresponding decimal code value that
decimal number.
