Help me please ?????​

Answer 1

Question : find whether they are rational or Irrational.

• $\sqrt{ \dfrac{2}{8} }$

• $\sqrt{ \dfrac{1}{4} }$

• $\dfrac{1}{2}$

• $0.5$

It's a rational number since it can be represented in the fractional format and denominator isn't equal to 0, and it also ends up as a terminating decimal (i.e 0.5).

• $\sqrt{2.56}$

• $\sqrt{ \dfrac{256}{100} }$

• $\dfrac{16}{10}$

• $1.6$

it's also a rational number ( same reason ) cuz it has terminating decimal place and can be represented in fractional format ( where denominator isn't equal to 0)

now just represent them on number line that's it .
