2,16×0.55×4.5÷2.7×0.15×1.2

Let's simplify the expression step by step: 1. Calculate \(2.16 \times 0.55\): \[ 2.16 \times 0.55 = 1.188 \] 2. Now, multiply by \(4.5\): \[ 1.188 \times 4.5 = 5.346 \] 3. Divide by \(2.7\): \[ 5.346 \div 2.7 \approx 1.97778 \quad (\text{for precision, you can use a calculator}) \] 4. Multiply by \(0.15\): \[ 1.97778 \times 0.15 \approx 0.29667 \] 5. Finally, multiply by \(1.2\): \[ 0.29667 \times 1.2 \approx 0.356 \] Thus, the result of the expression \(2.16 \times 0.55 \times 4.5 \div 2.7 \times 0.15 \times 1.2\) is approximately \(0.356\).
