1) (5¹/₄ - 6¹/₆)*(3¹/₄ - 0,55) = - 2,4755¹/₄ - 6¹/₆= ²¹/₄ - ³⁷/₆= ⁶³/₁₂ - ⁷⁴/₁₂= - ¹¹/₁₂
3¹/₄ - 0,55=3,25 - 0,55 = 2,7 = ²⁷/₁₀
(-¹¹/₁₂)ײ⁷/₁₀ = - ¹¹ˣ²⁷/₁₂ₓ₁₀ = - ¹¹ˣ⁹/₄ₓ₁₀ = - ⁹⁹/₄₀ = - 2,475
2) (2¹/₃ - 3¹/₄) * (2³/₄ - 0,95) = - 1,65
2¹/₃ - 3¹/₄=⁷/₃ - ¹³/₄ = ²⁸/₁₂ - ³⁹/₁₂ = - ¹¹/₁₂
2³/₄ - 0,95=2,75 - 0,95 = 1,8
(-¹¹/₁₂) × 1,8 = (-¹¹/₁₂) × ¹⁸/₁₀ = - ¹¹ˣ¹⁸/₁₂ₓ₁₀ = - ³³/₂₀ = - 1¹³/₂₀ = - 1,65
