A rational number requires all numbers after the decimal point to be recurring or fractional, whereas irrational numbers require them not to be neither. There are an infinite number of spaces after the decimal point that the numbers 0-9 can occupy, but for the purpose of this example let us limit that number to 2.
n.00, n.11, n.22, n.33, n.44, n.55 etc. are the only rational numbers in this setup as 2 decimal places serve as the limit, thus n.01 for example does not count as recurring nor to be able to adopt the m/n fraction. (In reality of course n.01 would be rational, but for a number system with 2 decimal places as the outer limit we can letthis serve as being irrational)There are 10 possible rational values between n and n+1 in total.
n.01, n.02, n.03, n.04,... etc. count as irrational numbers for the purposes of this example, as reaching the 2nd decimal place serves as the furthest the number can go, (In reality this would be infinite)and serves as reaching infinity for this case. There are 89 possible irrational values between n and n+1 in total.
As an example with up to 4 possible decimal places there would be 100 possible rational values and 9899 irrational values. With up to 8 decimal places the number of possible rational numbers would be 10000 and number of possible irrational values would be 99989999.
Stretching the number of possible decimal places up to infinity (i.e. reality) there would always be infinitely more possible irrational numbers than rational numbers.
At least... that's what I reckon the answer is...:P
