Answer:
A and D
Explanation:
The answers are A, B and D.
A- All fractions are rational numbers, so this is true.
B- As I said in A, all fractions are rational numbers, but not repeating decimals. For an example pi is a repeating decimal but is not rational. So this is not true.
C- Pi is not a rational number since it cannot be put as a fraction. The fraction for "pi" is 27/2, but this is only for a part of pi. So this is incorrect and not true.
D- The square root of 4 is 2, and integers are rational numbers so this is true.
E- A integer divided by 0 is undefined so this is incorrect and not true.
