Question

Determine if 0.8555555555555555 is rational or irrational and give a reason for your answer.

Answer 1

Answer:

It is an irrational number

Step-by-step explanation:

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

Answer 2

Answer:

It is irrational..

But we can express it in rational form

Step-by-step explanation:

Let 0.85 be x

Therefore,100x=85.5

10x=8.5

Therefore 100x-10x=85.5-8.5

90x=77

x=77/90.
