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?
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?)
To find the total number of pages in the book, we can use the information given.
First, we know that the girl has already read 3/5 of the book. Therefore, there are (5/5) - (3/5) = (2/5) of the book left to be read.
Next, we are given that there are 80 pages left to be read. We can set up a proportion:
(2/5) of the book = 80 pages
To solve this proportion, we need to find the value of 1/5 of the book.
To find the value of 1/5 of the book, we divide 80 pages by 2:
80 pages ÷ 2 = 40 pages
Now that we know that 1/5 of the book is equal to 40 pages, we can find the total number of pages in the book by multiplying by 5:
40 pages × 5 = 200 pages
Therefore, there are 200 pages 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
