Answer:

The correct options are;

[tex]4\dfrac{2}{3} - \dfrac{\sqrt{4} }{8}[/tex]

[tex]4\dfrac{2}{3} \div \dfrac{\sqrt{4} }{8}[/tex]

Step-by-step 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;

[tex]4\dfrac{2}{3} - \dfrac{\sqrt{4} }{8}[/tex] = [tex]\dfrac{53}{12}[/tex]

and

[tex]4\dfrac{2}{3} \div \dfrac{\sqrt{4} }{8}[/tex]
