While reading a book, Shara estimates that she is 75%
finished. If she has read 216
pages, then how long is the
book?

232 pages total.

Step-by-step explanation:

Let P = the number of pages in the book.

If Mary has 3/4 of the book left to read, then she has read 1 - 3/4 = 1/4 of the book.

P*(1/4) = 58

P = 4*58 =

Since the 58 read is 1/4 and the rest of the book would then be 3/4, imagine the pages split into 4 sections. Each section is 58 pages long. To find out how many pages all of them have together you can either add 58+58+58+58 or 58x4 for a quicker method. Either way should get you 232 pages.

58 pages are equal to 1/4th, 58*3 equals 174.  58 +174=232.  Drawing a pie diagram helps visualize the problem.
