39 POINTS THANK U SO MUCH I WILL GIVE U BRIANLIEST !!

1st, third, fifth

Step-by-step explanation:

sqrt(3) is irrational, so dividing it by 2 won't do anything

1/3 is rational

54 is not a perfect cube, so it's irrational

27^{1/3} = cbrt(27)=3, rational

sqrt(0.25)=0.5. 0.5*0.5=0.25. rational

pi is irrational(3.1415926535897932384626433832...)

1, 3, and 5 are irrational.

Step-by-step explanation:

is irrational because the square root of 3 is irrational, and if you divide it by 2, it will still be irrational!

2 is rational: the definition of a rational number is a number that can be expressed in the form a/b, where b is nonzero.

3 is not rational: 54 is not a perfect cube, therefore, its cube root will not be rational.

4 is rational. The square root of 0.25 is 0.5, which can be expressed in the form a/b, b is nonzero. 0.5 = 1/2!

5 is irrational. Pi is a famous irrational number, because it goes on forever without a pattern!

Hope this helps :) If you have any questions or concerns please feel free to reach out to me!
