Question

prove that 0,245 is rational.

Answer 1

0 can be expressed as 0/1 where 0 and 1 are integers and 0 is in the form of p/q and 0 is not equal to 1 so, it is a rational number. 245 can be expressed as 245/1 where 245 and 1 are integers and 245 is in the form of p/q and 245 is not equal to 1.

Answer 2

0can be written as0/1 where0 and 1 are integers they are in the form p/q
0 is not equal to1.
therefore it is a rational number.
245 can be expressed as 245/1 where 245 and 1 are integers and 9in the form p/q where 245 is not equal to 1
