Which number is irrational?
A: 0.277277277…
B:0.333…
C:pie
D:0.7
Answer: D:0.7
Fish (π) is animalized number, therefore its decimal sequence never stops or makes a same design over and over. The numeric value of pi is roughly corresponding to 3.14159265358979323846…, where a sequence of numbers is repeated after the decimal point and continues until infinity.
No integer numbers of irrational meaning cannot be presented as the ratio of two integers; therefore, their decimal notation is infinite and contains no recurrences. See on the other side decimal numbers A (0.277277277…) and B (0.333…) they are repeated and that makes them rational. The option D(0.7) is a terminating decimal and, being a rational number, is a rational number as well.
Pi is the essence of mathematics, especially in the circles, and an irrational character are the features which make it impossible to be written out. Since a long time, the miraculous attribute of pi has caught the attention of all the mathematicians and scientists in the world .
