Best Answer
If Osei has read 20% of the total number of pages in the book, we can use the proportion:
20 100 = 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:
20 x = 100 65 20 x=100*65
x = 100 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:
    20 100 = 65 x (20)/(100)=(65 )/(x)
  3. To solve for x x, we can cross-multiply:
    20 x = 100 65 20 x=100*65
  4. Simplifying the right-hand side, we get:
    20 x = 6500 20 x=6500
  5. Dividing both sides by 20, we get:
    x = 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.
