Question

0.6*5/6+(5/6-2/15):7/30

Answer 1

0,6 × ⁵/₆ + (⁵/₆ - ²/₁₅) : ⁷/₃₀ = 3,5
1) ⁵/₆ - ²/₁₅ = ⁵ˣ⁵/₃₀ - ²ˣ²/₃₀ = ²⁵/₃₀ - ⁴/₃₀ = ²¹/₃₀
2) 0,6 × ⁵/₆ = ⁶/₁₀ × ⁵/₆ = ⁶ˣ⁵/₁₀ₓ₆ = ⁵/₁₀ = 0,5
3) ²¹/₃₀ : ⁷/₃₀ = ²¹/₃₀ × ³⁰/₇ = ²¹ˣ³⁰/₃₀ₓ₇ = ²¹/₇ = 3
4) 0,5 + 3 = 3,5

Answer 2

To evaluate the expression, let's break it down step by step:

Step 1: Multiply 0.6 by 5, then divide the result by 6: 0.6 * 5 = 3 3 / 6 = 0.5

Step 2: Subtract 2/15 from 5/6: 5/6 - 2/15 = (55 - 22) / (6*15) = 23/30

Step 3: Divide the result from Step 2 by 7/30: 23/30 ÷ 7/30 = (23/30) * (30/7) = 23/7 ≈ 3.2857

So the final result of the expression 0.6 * 5/6 + (5/6 - 2/15) ÷ 7/30 is approximately 3.2857.
