The statement is an equation in word form, so to solve, write the statement as an equation. In the phrase "The quotient of a number and 9" let X represent "a number." The statement as an expression is X / 9. "Is the same as" indicates the two expressions are equal, and "the difference of 14 and 8" means 14 - 8.
Put it together and you get the expression X / 9 = 14 - 8. From here, you have to solve for X by simplifying the expression and multiplying both sides by 9.
X / 9 = 14 - 8
X / 9 = 6
9 (X / 9) = (6) 9
X = 36

Answer:
259 students
Step-by-step explanation:
First, find how many will check out science fiction books
350(0.14)
= 49
Find how many will check out sports books
350(0.12)
= 42
Subtract these amounts from 350
350 - 49 - 42
= 259
So, she should expect 259 students not to check out science fiction and sports books
