(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:** \(\boxed{468.86}\) Let me know if you'd like the answer rounded or in a different format!
