2.77 is a real number, it is not a natural number, and it is not a whole number.
A: real numbers
B: real numbers and natural numbers
C: natural numbers and whole numbers

Given sets:
D = {5, 6, 7, 8, 9, 10}, E = {1, 3, 5, 7, 9, 11}, F = {3, 6, 9, 12}
What is D n E?
I believe the question is what is D ∩ E, which is the elements that are as much in D as in E. This is {5,7,9}
A: {1, 3, 5, 6, 7, 8, 9, 10, 11}
B: {5, 7, 9}
