Respuesta :
all except pi are rational.
2.333... = 21/9
1.5 = 3/2
2.333... = 21/9
1.5 = 3/2
Answer: Third Option is correct.
Step-by-step explanation:
Since we have given that
1) 1.5- it is a rational number as it can be written in [tex]\frac{p}{q}[/tex] form.
i.e. [tex]1.5=\frac{15}{10}=\frac{3}{2}[/tex]
2) [tex]\frac{8}{9}[/tex]- It is a rational number as it is written in [tex]\frac{p}{q}[/tex] form.
3) 2.3 - It is a rational number as it can be written in [tex]\frac{p}{q}[/tex] form.
i.e. [tex]2.3=\frac{23}{10}[/tex]
4) pi - It is irrational number as it can't be written in [tex]\frac{p}{q}[/tex] form.
Hence, Third Option is correct.
