If Osei has read 20% of the total number of pages in the book, we can use the proportion:
$\frac{20}{100}=\frac{65}{x}$(20)/(100)=(65 )/(x)
where $x$x is the total number of pages in the book.
To solve for $x$x, we can cross-multiply:
$20x=100\cdot 65$20 x=100*65
$x=\frac{100\cdot 65}{20}=325$x=(100*65)/(20)=325
Therefore, the answer is D, 325. So Osei has read 65 out of 325 pages in the book.
Step-by-step solution:
1. Let x be the total number of pages in the book.
2. Osei has read 20% of the book, so we can set up a proportion:
$\frac{20}{100}=\frac{65}{x}$(20)/(100)=(65 )/(x)
3. To solve for $x$x, we can cross-multiply:
$20x=100\cdot 65$20 x=100*65
4. Simplifying the right-hand side, we get:
$20x=6500$20 x=6500
5. Dividing both sides by 20, we get:
$x=\frac{6500}{20}$x=(6500)/(20)
6. Simplifying, we get:
$x=325$x=325
Therefore, the answer is D, 325, and Osei has read 65 out of 325 pages in the book.
