Respuesta :
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
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
Answer: 286
Step-by-step explanation:
Let the number of non fiction books be 'x'
Then the number of fiction books = 11x
Total books in Mark's bookcase= 312
According to the given situation the equation will be
[tex]x+11x=312\\\Rightarrow12x=312..............[\text{combine like terms}]\\\Rightarrow\ x=26.......[\text{divide 12 on both sides}][/tex]
Hence, the number of non fiction books=26
and the number of Fiction books =[tex]11\times26=286[/tex]
