For this case, the first thing we must do is define a variable.
 x: unknown number that belongs to the real numbers.
 We then have the following expression:
 the quotient of nine and the sum of a number and one
 By writing the expression algebraically we have:
 
 Therefore, the expression is equivalent to:
 9 over x+1
 
 the following best describes the English expression:
