sure

she reads 30 pages of the book and she reads for 3 days, so 30 x 3 = 90

5/8 of the book are left, so she read 3/8 of the book. which means 3/8 of the book = 90 pages

you can use x as the length of the book, so 3/8(x) = 90

multiply both sides by 8/3:
x = 240

so there are 240 pages in the book
