Question 2
Between two rational numbers

A) There is no rational number
B) There is exactly one rational number
C) There are infinitely many rational numbers
D) There are only rational numbers and no irrational numbers

Answer 1

The answer is C.
Between two rational numbers, there are infinitely many rational numbers.
E.g $\frac{3}{5}$ and $\frac{4}{5}$ are two rational numbers, then $\frac{31}{50},\frac{32}{50},\frac{33}{50},\frac{34}{50},\frac{35}{50}$ .... are infinite rational number between them.
