How do you know if a decimal is rational or irrational?
A decimal is rational if it:either ends and doesn't go on forever; ORit is a repeating decimal.A decimal is irrational if it goes on forever and ever and never stops without repeating.The number: 5.77777777 is rational because it goes on forever, REPEATING the same number (the digit 7).It can also repeat a group of numbers, like the number: 8.789789789789789789See how the "789" is REPEATING over and over again and never stops? That is a rational decimal!
What number goes on forever?
A recurring decimal (caused by the denominator of a fraction have a prime factor other than 2 and 5) or an irrational number (such as √2) goes on forever.
What is 1000 divided by 30?
33.3333
What is the line over a decimal that goes on forever called?
periodic line
Is 1.4 rational or irrational?
Any number which can be written exactly with a limited set of figures is "rational". Numbers which cannot be written with a limited set, because the decimal number goes on for ever is "irrational". So 1.4 is rational because it takes only 2 figures to write its value exactly.
Reasons why pie is not a rational number?
their is no end to it... it goes on forever...
Is pi a rational or irrational number and why?
irrational since it goes on forever 3.1415926535898... and on and on and on
Is 21 a rational?
Yes. Any whole number is rational. An irrational number is one that goes on forever without repeating, like √2=1.414213...
Is 21 a rational number?
Yes. Any whole number is rational. An irrational number is one that goes on forever without repeating, like √2=1.414213...
Is the number pi that goes on forever with no repeating pattern rational or irrational?
pi is an irrational number. It can not be expressed as a ratio of two integers.
Is 3.24 rational or irrational?
3.24 is rational because rational numbers are any number... the only numbers not rational are ones that go forever in a random pattern (ex. 3.14159265...). 3.363636363636... is rational because it goes on in a pattern. Hope that helped :)
Is 5.7777 A rational number?
Yes. If you mean 5.7777 as a terminating decimal it is 57777/10000 If you mean 5.7777... as a recurring decimal where the 7 repeats forever it is 57/9 If a decimal number terminates or repeats one or more digits forever it is a rational number. Otherwise if a decimal number goes on forever but does not repeat any digits (eg √2 = 1.41421356...) then it is an irrational number.

Is half of one an rational number?
Yes, because the decimal ends. 0.5 ends, compared to an irrational number such as pi, which as far as we know, goes on forever.
Is -0.06 rational or irrational?
Rational because it can be simplified into -3/50. Irrational numbers are decimals that go on forever. For example, pi 3.141592653... goes on forever.
Is three an irrational number?
No, it is an integer, and therefor part of the rational number system. An irrational number is, if I remember correctly, a number that goes on forever, and doesn't have a pattern like π (pi)
What is full value of pi?
There is no 'full' value of Pi. It is a number, called an irrational number, that goes on forever.
