Daniel has read 180 pages this is 80% of the entire book how long is the book

If we take these numbers we can set it up in crops multiplication form to find the answer:

80. 180

- - = - - - then we cross multiply

100 x making 80x = 18000 then divide 18000 and 80 to get 225 meaning x=225 so Daniels book is 225 pages long

225 pages, its correct answer i did the math

180/80

x / 100

cross multiply;

180*100=18,000

divide with the amount left

18,000/80=225
