To solve the expression 3,6:(68,17 1\2-8 17\20+2,02)+2,751,6, let's break it down step by step:

Step 1: Simplify the innermost parentheses. 68,1*7 1\2 = 68.1 * (7 + 1/2) = 68.1 * 7.5 = 510.75

Step 2: Convert the mixed fractions to decimals. 8 17\20 = 8 + 17/20 = 8.85

Step 3: Simplify the expression inside the parentheses. (68.1 * 7.5 - 8.85 + 2.02)

Step 4: Perform the operations inside the parentheses. 68.1 * 7.5 = 510.75 510.75 - 8.85 = 501.9 501.9 + 2.02 = 503.92

Step 5: Calculate the multiplication and addition outside the parentheses. 3,6:(503.92) = 3.6 / 503.92 ≈ 0.007143 2.75 * 1.6 = 4.4

Step 6: Perform the final addition. 0.007143 + 4.4 ≈ 4.407143

Therefore, the solution to the expression 3,6:(68,17 1\2-8 17\20+2,02)+2,751,6 is approximately 4.407143.
