An irrational number is a number that is not rational.

Answer 2

Yeah, a rational number is any number can be written as a division of 2 non-fraction or 2 non-decimal numbers. If its impossible to express a number without needing to make it a ratio of fractions or a ratio of decimals, then its irrational.

@Psymon example, please

Answer 4

Well, its what math student said, a number that can be expressed as a division of two integers. Its just an integer is a number that can be written without fractions or decimals. So 2 numbers, that are not fractions or decimals, can be divided to make a rational number. All numbers that can be expressed in this way are rational.
