A book has 255 pages. Of those pages, 74 have pictures on them. There are 17 students in a class and each student has to read out an equal number of pages from the book during the English lesson. What is the total number of pages that will be read out by the first four students in the class?

someone, please help me out

Pages to be read: 255-74 = 181

pages read per student = 181/17 = 10.65 ? ,
(Was expecting a whole number.)

pages read by 4 students = 181/17*4 = 42.6 pages
