a number is a ( n) ___ if it can be written in the form a/b where a and b are intergers and b =/ 0

Wouldn't it be whole number?

4/5 is not a whole number.

A number which can be expressed in the form of a/b (a and b are integers) is a rational number.

Those that cannot are called irrational numbers, namely the digits after the decimal point do not repeat. Examples are π, √2, etc.

Thank You!!

You're welcome!

No, a number that can be written in the form a/b, where a and b are integers and b ≠ 0, is actually called a "rational number."

A rational number is any number that can be expressed as a fraction or a ratio of two integers. This includes whole numbers, integers, and decimals that terminate or repeat. For example, 3/5, -2/7, 0, and -5 are all rational numbers.

Whole numbers, on the other hand, are a subset of rational numbers. Whole numbers include all positive integers (1, 2, 3, ...) and zero (0). So while whole numbers are indeed examples of rational numbers, not all rational numbers are whole numbers.
