To solve this expression, we need to follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to simplify the expression step by step:

Start by simplifying within the innermost parentheses:
(1×7/3 + 2.5) = (7/3 + 2.5) = (2.333 + 2.5) = 4.833

Substitute the result back into the expression:
9 - 3×5/1 × 4.833/2 × 7/1

Next, simplify the multiplication and division from left to right:
9 - 3×5 = 9 - 15 = -6
-6/1 = -6
-6 × 4.833 = -28.998
-28.998/2 = -14.499
-14.499 × 7 = -101.493

Therefore, the final answer to the expression 9 - 3×5/1×(1×7/3+2,5)/2×7/1 is -101.493.
