Final answer:
To find the expressions that have a quotient of 9, divide the numerator by the denominator for each expression and see if the result is 9. The correct options are c, d, and e.
Step-by-step explanation:
To find the expressions that have a quotient of 9, we need to divide the numerator by the denominator for each expression and see if the result is 9. Let's go through each option:
a. 2703 ÷ 1 = 2703, which is not 9
b. 250 ÷ 25 = 10, which is not 9
c. 270 ÷ 30 = 9, which is 9
d. 207 ÷ 23 = 9, which is 9
e. 189 ÷ 21 = 9, which is 9
So, the correct options are c, d, and e. These expressions have a quotient of 9.
