7/9 would be irrational, I think.
OpenStudy (anonymous):

OpenStudy (anonymous):
Well, 7/9 cannot be expressed as a decimal, since it is 7.7777 never ending.

7.8 Wouldn't be an irrational number because it can be written as a simple fraction 39/5
OpenStudy (anonymous):
An irrational number is one that doesn't have a simple fraction form.

7.9 = 79/10 = rational.

\[\sqrt{60} = 7.745966692 = Irrational\]
OpenStudy (anonymous):
YAY I GOT IT!!!!!!!!!! \(^-^)/
OpenStudy (anonymous):
So the square root of 60 would be an appropriate answer.
