(2,76*2,4:0,96-1,02):2,1+0,4

Let's solve the expression step by step:

Given expression: (2.76 * 2.4 ÷ 0.96 - 1.02) ÷ 2.1 + 0.4

1. Calculate 2.76 * 2.4: 2.76 * 2.4 = 6.624

2. Divide the result by 0.96: 6.624 ÷ 0.96 = 6.9

3. Subtract 1.02: 6.9 - 1.02 = 5.88

4. Divide by 2.1: 5.88 ÷ 2.1 ≈ 2.8

5. Add 0.4: 2.8 + 0.4 = 3.2

Final answer: 3.2
