Question

Without simplifying Select all the expressions that represent a rational number( someone helppppppp)

Answer 1

The correct options are;

`4(2)/(3) - (√(4) )/(8)`

`4(2)/(3) / (√(4) )/(8)`

Explanation:

We note that a rational number is one that can be expressed as a ratio of two integers a and b

An irrational number is one that cannot be expressed as a ratio of two integers. Example of an irrational number is √3

Also an irrational number divided by a rational number is an irrational number, therefore, we have, the expressions without irrational numbers, which are;

`4(2)/(3) - (√(4) )/(8)` =
`(53)/(12)`

and

`4(2)/(3) / (√(4) )/(8)`
