If the total number of pages in a book,62%have pictures and the rest have no pictures. there are 310 pages with pictures in the book

a) what is the total number of pages in the book

b) how many pages in the book have no picture

500 pages, because 500 times .62 equals 310. 500 -310 = 190. Therefore, 500 total pages, and 190 pages without pictures

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
