(2,88:0,48•7,5-5,6)•((5,4-2,9)•(4,7+0,06))

Let's carefully evaluate the expression step-by-step:

Expression: (2.88 ÷ 0.48 * 7.5 - 5.6) • ((5.4 - 2.9) • (4.7 + 0.06))

Step 1: Simplify inside brackets

• First part: (2.88 ÷ 0.48 * 7.5 - 5.6)
• Second part: (5.4 - 2.9) and (4.7 + 0.06)

Calculating the first brackets:

1. 2.88 ÷ 0.48 = 6

2. 6 * 7.5 = 45

3. 45 - 5.6 = 39.4

Calculating the second brackets:

4. 5.4 - 2.9 = 2.5

5. 4.7 + 0.06 = 4.76

6. Now multiply: 2.5 * 4.76 = 11.9

Final calculation:

7. Multiply the two main results: 39.4 * 11.9 =

Let's do this multiplication:

• 39.4 * 11.9

Break it down:

= 39.4 * (10 + 1.9)

= 39.4 * 10 + 39.4 * 1.9

= 394 + (39.4 * 1.9)

Calculate 39.4 * 1.9:

• 39.4 * 1.9 = (39.4 * 2) - (39.4 * 0.1)

• 39.4 * 2 = 78.8

• 39.4 * 0.1 = 3.94

• Subtract: 78.8 - 3.94 = 74.86

Add back to previous sum:

394 + 74.86 = 468.86

Final answer:

\(\boxed{468.86}\)
