A girl reads 3/5 of a book. She finds that there are still 80 pages left to be read .how many pages are there in the book?

If she read 3/5 of the book, then she still has 2/5 of the book to read
2/5 of book = 80
then 1/5 of book = 40 and
5/5 of book = 200 
1/5 is 40 pages so 40x5=240 so there are 240 pages in the book

A boy reads 2/5 part of a book .he finds that there are still 45 pages to read to complete the book .how many total pages are there in the book?)
