The question reads as "At a certain pizzeria, 1/6 of the pizzas sold were cheese, and 1/5 of the OTHER pizzas sold were pepperoni. If Brandon bought a randomly chosen pizza from the pizzeria that week, what is the probability that he ordered a pepperoni?

The answer is 1/6.

However, the 1/6 is the answer for 1/5 OF 5/6. How do conclude that the 1/6 is the probability based on all the pizzas sold.

Because your value of 1/5 of 5/6 is just an abbreviated way of saying 1/5 of 5/6 OF ALL THE PIZZAS.
