The total number of pages in the book is 70 if Joe has read 30% of the book and he has 49 more pages to finish.
What is the percentage?
It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We have:
Joe has read 30% of a book.
Remaining number of pages = 49
Let's suppose the total pages are x
The remaining % = 100% - 30% = 70%
[tex]\rm 70\% \ of \ x =40[/tex]
[tex]\rm \frac{70x}{100} =49[/tex]
x = 70 pages
Thus, the total number of pages in the book is 70 if Joe has read 30% of the book and he has 49 more pages to finish.
