Any terminating or repeating decimal number can be converted easily into the form of p/q: a ratio of two integers. If it can be written in that form then it is rational.

Why cant irrational numbers be represented in decimal form?
But irrational numbers are decimals that can't be expressed as fractions
What is the mathematical symbol for an irrational number?
it's Q Bar. i cant find a symbol for it on the keyboard. but its basically like The rational Symbol (Q) with a horzontal line on top of it.
Is 1 8 the decimal for 0.12?
No, 1 8 cant be a decimal.
Are irrational numbers real numbers?
A mathematical approach:Yes they are. Irrational numbers are very real, for example - the square root of two - which is irrational (but can be plotted in a number line without difficulty with a compass and straight edge). All numbers you can think of (even if you cant white them out) are real numbers.They are real, but they can't be expressed as fractions.A philosophical approach:According to ME, there should be a limit. If there is a number which is not ending, we can't say that it is a number because it has not ended yet, its not a complete number. That's why, any number which is not ending is not a number, so irrational numbers and some rational numbers are not numbers and we can't plot them on real line, no matter how much depth we are into it. If there is a number 1.0000... (100 million 0's) ...1, we can plot it by dividing real line into required many parts but we cant plot a number like 1.1111....1111....(up to, we don't know), actually that's not a number yet.Maths should be changed.
What is nine thirds as a decimal?
It cant be written as a decimal apart from 3.0 which is a whole number. The fraction is basically saying that there are 9 thirds which equals three. Three thirds equals one because three thirds equals a whole.
Why cant irrational numbers be represented in decimal form?
But irrational numbers are decimals that can't be expressed as fractions
What is a number that cant be written as a fraction or decimal?
Irrational, possibly transcendental
Why cant irrational number be presented as a decimal?
All irrational numbers are non-terminating decimals that can't be expressed as fractions
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!
Can the difference of two rational numbers can be irrational?
No irrational numbers don't have patterns and cant be expressed as a ratio so you cant even subtract the number. Ex: 22/7 - sqrt(2), you wont be able to find the difference since you cant even put it in a complete number.
How do you change 0.5 to a decimal?
0.5 is a decimal so therefore you cant change a decimal to a decimal. But, 0.5 as a number is 5.
What is an irrational number between 5 to 10?
An irrational number is a number that cannot be expressed as a fraction. So whole numbers and fractions are out. You can then just make a number like 6.34298374923743333333. You put a bar over the 3 so it repeats, and the number cant be expressed as a fraction, makin git an irrational number.
Is 0.151155111555.Rational Or Irrational?
This number is rational as 0.151155111555 = 151155111555 / 1000000000000 = 151291 / 1000899 if 0.151155111555 is the beginning of the number 0.151155111555111155551111155555.... then it's irrational as the decimals are not repeating and the sequence is infinite
What number cant be represented by roman numerals?
Any number that has a fraction that is not duodecimal (twelfths or factors thereof).
What does irrational?
irrational means something that cant make a fraction !!1
Why cant irrational be represented in decimal form?
A decimal number is eitherterminating,repeating, ornon-terminating and non-repeating.The last of these can never be written out since it has infinitely many digits with no way of abbreviating them. A terminating decimal number is one with at most n digits after the decimal point (where n is finite). Such a number is equivalent to a rational number whose denominator is 10^n. The number is therefore rational.For example, 0.23568 = 23568/100000. It can be simplified but that is not relevant here.A number with a decimal representation with a recurring string of length m (where m is finite) is a rational number whose denominator is a 10^k multiple of 10^m-1 or 99...9 (m times). Here k is related to when the repeating sequence starts.For example, consider 1.23142857142857... (with the 6 digit sequence 142857 repeating)Let f = 1.23142857142857...then 100f = 123.142857142857...and 100f*1000000 = 123142857.142857142857...So that 999999*100f = 123142857-123 which is an integer.f is, therefore a ratio of two integers and so is a rational number.So that only leaves the irrational numbers for infinitely long decimal representations with no recurrence.

i have no idea cant remeber jitter bug_09
