Jada has read 3/5 of a book, equaling 75 pages. By setting up the proportion 3/5 = 75/x and solving for x, we find the total number of pages in the book to be 125, which is choice D. therefore, option D is correct
Jada has read 3/5 of a book which corresponds to 75 pages. To find out the total number of pages in the book, we can set up a proportion where 3/5 represents the part of the book she has read and x represents the total number of pages in the book. The equation would be 3/5 = 75/x.
We can solve for x by cross-multiplying:
- (3/5) * x = 75
- x = 75 / (3/5)
- x = 75 * (5/3)
- x = 25 * 5
- x = 125 pages
So, the total number of pages in the book is 125 pages, which corresponds to answer choice D.
