it is irrational
rational
yes
A repeating rational number is an irrational number. An irrational number is an number that has no definite end. 4.15 has a definite end and is therefore a rational number.
No. A rational number is any terminating numeral. A repeating decimal is irrational.
If the decimal of a fraction either terminates or ends with a repeating cycle of digit(s) then it is a rational number; otherwise it does not terminate nor does it have a repeating cycle of digit(s) at the end and is irrational. 0.12345 terminates as so it rational If that was repeating, as in 0.123451234512345..., then it is still rational.
A repeating decimal is rational.

It is a rational number.
1.121212121212...is rational. It is a repeating decimal and it is rational.
A repeating rational number is an irrational number. An irrational number is an number that has no definite end. 4.15 has a definite end and is therefore a rational number.
0.1121231234(not repeating) is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
As given as ' 0.151515 . it is a terminating decimal and can be converted to a fraction/ratio Hence 0.151515/ 1.000000 = 0151515/1000000 = 151515/1000000 = 30303/200000 is the fraction. However, if you mean 0.151515 recurring to infinity, it is also rational. It should be written as ' 0.151515.... ' Note the three or more dots after the last digit. To convert to a ratio/quotient/fraction Let P = 0.151515.... 100P = 15.151515.... Subtract 99P = 15 Note the recurring decimals subtract to zero. P - 15/99 Reduce by '3' P = 5/33 The ratio/fraction. NB When reading decimal numbers. If it recurs to infinity, AND the decimal digits are in a regular order , as in this case at '151515' , then it is NOT irrational. e.g. 0.123123123.... Is rational or 0.1234512345..... is rational etc., because the decimal digits are in a regular order, and can be converted to a ratio/fraction/quotient.
