Find an irrational number that is between 7.7 and 7.9. Explain why it is irrational. Include the decimal approximation of the irrational number to the nearest hundredth.

Answer 1

An answer could be 7.7899775796… because it is not a terminating or repeating decimal.

Answer 2

Answer:

$\sqrt{60}$, which is 7.745966692414834 and continuing.
