We were being invited by them.

$\sf\underline{Rules \: for \: conversion \: :}$

》Whenever a past continuous tense is used, we use were/was + being + 3rd form of the verb

For example :-

Active - I was pulling the door

Passive - The door was being pulled by me.

》Always the 3rd form of the verb is used.

》Format without question : Subject + helping verb + 3rd form of the verb + by + doer.

For example :-

Active - She has cooked the food.

Passive - The food was cooked by her.

》Format with a question : By + Doer + helping verb + 3rd form of verb + Subject.

For example :-

Active - Who teaches you English?

Passive - By whom are you taught English?
