Answer: A, B and C
Explanation:
A rational number is something that can be made with a fraction.
A fraction is a fraction, so A is correct.
A terminating decimal can be made from a fraction, for example 1/2 = 0.5 which is a terminating decimal so B is correct.
A repeating decimal can also be made from a fraction, for example 1/3 = 0.333333... so C is correct.
An imaginary number doesn't actually really exist, so it can't be represented through a fraction.
