Aclassmate says that 0.285714 repeating is not a rational number because it does not terminate. explain her error.
i need answering this

It is a rational number because it can be put into a fraction using ordinary whole numbers.

On the other hand a fraction containing ordinary whole numbers isn't available for pi. Therefore, pi is irrational.

A number that is repeated periodically is an irrational number! Error lies in the fact that if we have a decimal value and a string repeat it (at some time) it is an irrational number, that is, it can not be represented as a fraction. It is scientifically proven.

The point (5, 10) will work for the rule y=x+5.y= 10 x= 510=5+510=10therefore the ordered pair (5, 10) works for the rule
