1 79 462 8,947.18496 Any number that you can completely write down on paper using digits is rational. (And some of them that you can't are also rational.)
Approximately 8.8 repeating. While true, the answer is misleading in the sense that a repeating decimal implies a rational number whereas sqrt(79) is irrational. Sqrt(79) = 8.888194..
Yes
0.79 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its equivalent, in rational form, is 79/100 which cannot be simplified.
