Step 1: First, perform the multiplication and division operations.
5 * 5 = 25
25 / 7 is approximately 3.5714
Step 2: Next, perform the multiplication operation in the last part of the expression.
3 * 9 = 27
Step 3: Now, substitute the results back into the original expression:
3.5714 + 8 - 27
Step 4: Finally, perform the addition and subtraction operations.
3.5714 + 8 = 11.5714
11.5714 - 27 is approximately -15.4286
