(9 ¹/₄ - 8 ²/₃) * 1 ⁵/₇ = 1
1) 9 ¹/₄ - 8 ²/₃ = ³⁷/₄ - ²⁶/₃ = ⁽ ³⁷*³ ⁻²⁶*⁴⁾/₁₂ = ⁽¹¹¹⁻¹⁰⁴⁾/₁₂ = ⁷/₁₂
2) ⁷/₁₂ * 1 ⁵/₇ = ⁷/₁₂ * ¹²/₇ = 1
(3 ²/₅ + 1 ⁵/₇) * 11 ²/₃ = 59 ²/₃
1) 3 ²/₅ + 1 ⁵/₇ = ⁽¹⁷*⁷ ⁺ ¹²*⁵⁾ /₃₅ = ⁽¹¹⁹⁺⁶⁰⁾/₃₅= ¹⁷⁹/₃₅ =5 ⁴/₃₅
2) 5 ⁴/₃₅ * 11 ²/₃ = ¹⁷⁹/₃₅ * ³⁵/₃ = ¹⁷⁹/₃ = 59 ²/₃
2 ³/₄ * (2 ¹/₂ - 1 ²/₅ ) = 3,025
1) 2 ¹/₂ - 1 ²/₅ = 2 ⁵/₁₀ - 1 ⁴/₁₀ = 1 ¹/₁₀
2) 2 ³/₄ * 1 ¹/₁₀ = ¹¹/₄ * ¹¹/₁₀ = ¹²¹/₄₀ = 3 ¹/₄₀ = 3,025
