To solve the given expression, we'll follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Let's break down the given expression step by step:

1. Convert mixed numbers to improper fractions: - 2 5/9 can be written as (2 * 9 + 5) / 9 = 23/9 - 2 1/4 can be written as (2 * 4 + 1) / 4 = 9/4 - 6 2/9 can be written as (6 * 9 + 2) / 9 = 56/9

2. Multiply the fractions: - 23/9 • 9/4 = (23 • 9) / (9 • 4) = 207/36

3. Multiply the whole number by the fraction: - 207/36 • 3/8 = (207 • 3) / (36 • 8) = 621/288

Therefore, the solution to the given expression 2 5/9 • 2 1/4 + 6 2/9 • 3/8 is 621/288.
