The difference between two rational numbers must be a rational number. Is this statement true?
A rational number is a number that can be written in the form a/b where a is an integer and b is a non-zero integer.
We will use the definition of the rational number to explain the difference between two rational numbers.
Consider two rational numbers, 4/5 and 1/5
Difference = 4/5 - 1/5 = 3/5 which is a rational number.
