Answer 1

Irrational means that it cannot be written as a simple fraction, right? So, which of the answers fit that category? Any ideas?

Answer 2

umm maybe 3 or 4

Answer 3

3 and 4 are definite. What about B? It can be written as a fraction but what about the square root?

Answer 4

\[\sqrt{\frac{ 3 }{ 4 }} = \frac{ \sqrt{3} }{ \sqrt{4} } = \frac{ \sqrt{3} }{ 2 }\]

So, 2 is definitely rational but what about square root of 3?
