A5 / a1 =  r^4  = 324/4 

So r^4 = 81

r = +/- 3

If  r = 3 :-

S5  = 4 *  (3^5-1) / (3-1)  = 484

so r = 3 Answer

What is the total number of pages in the e-book
Dafna1 [17]

Answer:

Step-by-step explanation:

If 75 percent is 180 pages, we need to find the amount of pages the remaining 25 percent of the book has and add that to 180 pages because 75+25 = 100. 75/3 is equal to 25.

75:180 =

25:60.

By dividing the ratio, we found out that if Logan read 25 percent of his book, he would have read 60 pages.

180 + 60 = 240.

The total number of pages is 240
