0,3×(²³/₂₅-0,4×¹/₅)-0,1 = 0,1520,4×¹/₅ = 0,4×0,2 = 0,08
²³/₂₅ - 0,08 = 0,92 - 0,08 = 0,84
0,3 × 0,84 = 0,252
0,252 - 0,1 = 0,152
****************
(-5,8)-14,28×(-⁵/₇)-30,04 = - 25,64
14,28×(-⁵/₇) = ¹⁴²⁸/₁₀₀×(-⁵/₇) = - ¹⁴²⁸ˣ⁵/₁₀₀ˣ₇ = - ²⁰⁴/₂₀ = - 10,2
(-5,8) - (-10,2) = -5,8 + 10,2 = 4,4
4,4 - 30,04 = - 25,64
*****************************
(-1⁵/₉×2¹/₇+1⁷/₁₂)×1¹/₇ = - 2
-1⁵/₉×2¹/₇ = -¹⁴/₉ × ¹⁵/₇ = - ¹⁴ˣ¹⁵/₉ₓ₇ = - ¹⁰/₃
- ¹⁰/₃ +1⁷/₁₂ = - ¹⁰ˣ⁴/₁₂ +¹⁹/₁₂ = - ⁴⁰/₁₂ +¹⁹/₁₂ = - ²¹/₁₂ = - ⁷/₄
- ⁷/₄ × 1¹/₇ = - ⁷/₄ × ⁸/₇ = - ⁷ˣ⁸/₄ₓ₇ = - ⁸/₄ = - 2
*********************************
⁹/₁₄×(-2¹/₃)+(-3³/₄)×⁵/₆ = - 4⁵/₈
⁹/₁₄×(-2¹/₃) =⁹/₁₄×(-⁷/₃) = - ⁹ˣ⁷/₁₄ₓ₃ = - ³/₂
(-3³/₄)×⁵/₆ = (-¹⁵/₄)×⁵/₆ = - ¹⁵ˣ⁵/₄ₓ₆ = - ²⁵/₈
(-³/₂) + (-²⁵/₈) = -³/₂ -²⁵/₈ = -¹²/₈ -²⁵/₈ = ⁻¹²⁻²⁵/₈ = -³⁷/₈ = -4⁵/₈
