Mark has 312 books in his bookcases. He has 11 times as many fiction as nonfiction books. How many fiction books does Mark have?
1 answer:
11x represents the fiction
X represents the nonfiction book
11x+x=312
12x=312
Divide both by 12
X=26
To find the fiction you have to do 11 times 26
11•26=286
To check the answer you add 286 and 26
If it adds up to 312 the answer is correct
