Answer 2

4. 5 pages 
The answer is 5 pages because if Kosta read 1/4 of an 8 page chapter, she read 1/4*8 of a chapter, because of means multiply, which equals 2 pages. Add the three pages Christina read, and you'll get 2+3=5 pages.
6. 9 sections
The answer is 9 sections because eating 1/3 of the 12 sections means eating 12*1/3 of the sections, because of means multiply, which equals to 4, and if you add that to the sections you ate, you'll get 4+5=9 sections.
Hope this helped!
