Of the 36 students in the book club .five ninths Of the students prefer adventure books to historical books. How many of the students in the book club prefer historical books?



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.
