Answer 2

Step-by-step explanation:

let the book contains x parts

noor read 1/22 of x parts on the 1st day = x/22

remaining parts after 1st day = x - x/22 = 21x/22

on the second day noor read 5/9 of the remaining

⇒ second day noor read 5/9 × 21x/22 = 35x/66

remaining parts after 2nd day = 21x/22 - 35x/66 = 28x/66 = 14x/33

the part of the book is left to be read is 14/33
