To solve the problem, we need to follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) in order to simplify the expression.

1) First, let's simplify each part of the expression:

960 ÷ 3 = 320600 + 6 • 7 = 600 + 42 = 6422,780 ÷ 6 = 463.33 (rounded to 2 decimal places)6,945 - 9 • 5 = 6,945 - 45 = 6,900320 ÷ 642 = 0.49844 (rounded to 5 decimal places)

Therefore, the final result of the expression is approximately 0.49844.
