Question

What is irrational number and is 4/3 a irrational number??

Answer 1

`\displaystyle\\Answer: \ (4)/(3) \ isn`t\ an\ irrational\ number`

Step-by-step explanation:

An irrational number is an infinite non-periodic fraction

`\displaystyle\\(4)/(3)=1(1)/(3) \\\\(4)/(3) =1.333333...\\\\(4)/(3)=1.(3)`

1.(3) - is an infinite periodic fraction

`\displaystyle\\Hence,\ (4)/(3) \ isn`t\ an\ irrational\ number`

Answer 2

Answer: 4/3 is not irrational, it is rational

Step-by-step explanation:

A rational number is a ratio, or fraction, of two integers. The denominator cannot be zero.

4/3 is rational since it's the ratio of the integers 4 over 3.

Since it is rational, it is not irrational. The term "irrational" literally means "not rational". Therefore, a real number is either of those options, but not both simultaneously.

A famous example of an irrational number is
`\pi \approx 3.14...` because it cannot be written as a fraction of two integers. We can get approximations like 22/7, but never manage to capture the full value of
`\pi` with a single fraction.

Another example of an irrational number is
`√(2)`
