Answer 1

Answer:

4480 pages

Step-by-step explanation:

Fraction of the book read = 5/8

Find the fraction of the book not read:

Fraction = 1 - 5/8 = 3/8

Find the number of pages in the books

Fraction not red = 3/8

Pages not read = 1680

3/8 of the book = 1680

1/8 of the book = 1680 ÷ 3 = 560

8/8 of the book = 560 x 8 = 4480

Answer: There are 4480 pages in the book

Answer 2

Let Total Page of book=x

After Reading 5/8 of Book 1680 pages Left
Readed Page=5/8x

Means If we Subtract Total Page and Pages readed
will be=1680

A/Q
x-5/8x=1680
8x-5x/8=1680
3x/8=1680
3x=1680×8
x=1680×8/3
x=4480

Total Pages=4480
