Trey buys five different types of coffee beans. He buys 1/2 pound of vanilla, 8/9 pound of Columbian, pounds 2 1/4 pounds of mild blend, 1 1/2 pounds of dark roast, and 3 2/3 pounds of hazelnut. On his next visit to the store, Trey buys 1/4 of the amount of Columbian coffee beans that he bought last time. How many pounds of Columbian coffee beans does he buy?
8/9 + (1/4) * 8/9
= 8/9 + 2/9
= 10/9
= 1 1/9
