A rational number is one that can be expressed as ratio(or fraction) of two integers: given integers a & b (with b ≠ 0), then the fraction a / b (or a ÷ b) will be a rational number. We need to specify that b not equal to zero, as division by zero is not defined (well not for most math applications).
So Irrational Numbers such as pi, e, and square root of 2: cannot in any way be resolved into a fraction of two integers. All rational numbers can. Examples are:
- 0 is rational, let a = 0, b = 1, or any other non-zero integer: 0/1 = 0
- Whole numbers are rational: 1/1 = 1; 2/1 = 2; 100/25 = 4, etc.
- Negative integers are also rational: (-4)/(2) = -2, or (20)/(-5) = -4
- All fractions (proper and improper) which have integers in the numerator, and non-zero integer in denominator, as well as mixed numbers are rational {positive and negative} will be rational numbers.

88 is the ratio of 88 and 1. That makes it rational.
What makes 0.33 a rational number?
0.33 = 33/100. The number can be expressed as a ratio of two integers and, therefore, it is a rational number.
What makes number .3596 a rational?
It is a rational number because it can be expressed as a fraction in the form of 899/2500 in its simplest form
Is -144 over 4 a rational number?
Yes. It's the ratio of -144 and 4. That makes it a rational number by definition.
Is -4 a rational number?
A rational number is a number that has a definite end. For example, pi is never ending and is therefore an irrational number. -4, however, has a definite end. This makes it a rational number.
What kind of number is 1.2?
the number 1.2 is a real and rational number
Is pie a rational number?
No. Pie is potentially never ending. This makes it an irrational number.
What are all numbers than make a square?
All numbers can make a square. Every real number makes a positive real square. Every rational number makes a rational square. Every integer makes a perfect square.
Is 3.456 a rational or irrational number?
It is a rational number. It can be written as a fraction.
