Answer 2

•During the voice change, first always note the subject and object

•Subject - I(me)
Object - It

•In voice change, Subject and objects are interchaged.

•Note the tense form.
Accordingly, change its voice.

•'I have asked it to follow us about' is in present perfect. So it changes to present perfect continuous.

The voice change is :

It has been asked by me to follow us about.
