Answer :
You have to make a tape diagram and divide it in to 9 parts because it is 5 out of 9 then you will make a bracket pointing to only 4 parts of the tape diagram then you do 36/9 and it will equal 4 so put 4 in to each part and so 4 x 4 is 16 so the answer is 16 people prefer historical books
You could draw it out such as: x x x x x x x x x
x x x x x x x x x
x x x x x x x x x
x x x x x x x x x
Now you have nine groups of 4 which equals 36
Now 5/9 would be five of the nine groups. Each group have 4 students so 4 x 5 = 20 students like Adventure books. Then take 36 - 20 = 16, which means 16 students like historical books.
