To solve the expression 3.8*(-2.75)+13.6:1.7:(4.3-7.85):7.1, let's break it down step by step:

Step 1: Evaluate the expression inside the parentheses: 4.3 - 7.85 = -3.55

Step 2: Evaluate the division operation from left to right: 13.6 / 1.7 = 8

Step 3: Substitute the evaluated value into the expression: 3.8 * (-2.75) + 8 : (-3.55) : 7.1

Step 4: Evaluate the multiplication: 3.8 * (-2.75) = -10.45

Step 5: Evaluate the division operation from left to right: 8 / (-3.55) = -2.2535211267605635 (approx.)

Step 6: Evaluate the final division operation: -2.2535211267605635 / 7.1 = -0.3175352112676056 (approx.)

Therefore, 3.8*(-2.75)+13.6:1.7:(4.3-7.85):7.1 is approximately equal to -0.3175.
