Answer:
120 pages
Step-by-step explanation:
add all the ratio
1+3+4= 8
divide all the pages(240) to the total number of the ratio(8)
240÷8
=30
multiply the answer(30) to each of the numbers in the ratio(1:3:4)
1 × 30 = 30
3 × 30 = 90
4 × 30 = 120
add all to check if right
30+90+120 =240
120 pages is on the longest chapter
