To find the total number of pages in the book, we can set up a proportion. Let's represent the total number of pages in the book as "x".
We know that Jocelyn has read 156 pages, which is 4/5 of the entire book. Therefore, we can write the following proportion:
156/x = 4/5
To solve for "x", we can cross-multiply and then solve for "x":
5 * 156 = 4 * x
780 = 4x
Divide both sides of the equation by 4 to isolate "x":
780/4 = x
x = 195
Therefore, the book has 195 pages.
