YES!!! Because it can be converted to a RATIO.

Let 10P = 8.33333....

100 P = 83.3333....

Subtract

90P = 75

P = 75/90

Cancel down by '5'

P = 15/18

Cancel down by '3'

P = 5/6 ( A RATIO).

This is the fraction in its lowest terms.

NB Irrational Numbers are 'pi = 3.141592..... . Sqrt(2) = 1.414213562....

Casually irrational numbers have the decimals going to infinity, and there is no regular order in the decial digits. As the name suggests, irrational numbers cannot be converted to a ratio (fraction).
