Is the number 23 an irrational number or a rational number?
Rational.All counting numbers (1, 2, 3 etc.) are rational. In fact many fractions/decimals are rational too. Rational just means that we know when the numbers stop.A good example of an irrational number is Pi, which equals 3.14159265358979.... and it just keeps going. No one knows the exact number of pi because as far as anyone can tell, the numbers keep going forever without any proper repeating pattern.
Why do you have to put a repeating decimal symbol?
You have to put that because if you cut the number off by not putting it there, you are not showing how the number keeps going. To have the number be more accurate, you should put in the repeating number symbol.
Is 1.234567891011121314 a rational number?
Yes it is. Any number that you can write completely using digits, and a decimal point or a fraction bar if you need one, is rational. If the number you wrote in the question is all there is to it, and it doesn't keep going on forever, then it's rational.
Consider the decimal do you think this decimal represents a rational number why or why not?
If the decimal terminates or repeats, it is rational. If it keeps on going forever, it is irrational.
Is 0.15783623 an irrational number?
