Answer 1

Answer:

Total pages of the book are 180.

Step-by-step explanation:

pages read = 7/9

pages left = 2/9

let p be the total no of pages of the book

2/9 x p = 40 ( 2/9 of the pages of book is 40)

p = 40 ÷ 2/9

p = 40* 9/2

p = 20*9

p = 180

Total pages of the book are 180.

Answer 2

Answer:

Step-by-step explanation: we can do this as this :

let the total number of pages be x,

then left over pages will be in the fraction of 9/9 - 7/9 = 2/9

then we get the following equation:

2/9 * x = 40

x = 40 * 9/2

therefore x = 180
