What is the figure? Send a pic or something, please.
The question is asking to state on how to use the distributive property to check the binomial factor when a trinomial has been factored. In my calculation and further research, I would say that the answer would be that you have to split one of the binomial and then apply the distributive property.
Let number of non/fraction books =x
Then number of fiction books=11x
So, we form the equation x+11x=312
12x=312 x=26 so mark has 26*11=286 fiction books
