A)
D)
===========================================
Explanation:
Choices B and C are rational because we can simplify them to form a fraction of integers.
Any rational number is of the form P/Q where P,Q are integers and Q is nonzero.
So we can rule out choices B and C.
---------------
Choice A on the other hand cannot be written as a fraction of integers. The 5 isn't a perfect square, which makes irrational.
The same can be said about which is roughly equal to 3.14; the decimal digits go on forever without a known pattern.
Choice A and choice D are the two answers.
----------------
If we know the pattern of the decimal digits, then we can turn the decimal number into a fraction of integers
The number -0.777, where the 7s go on forever, converts to the fraction -7/9
That means we rule out choice E.
