(2⁷/₁₂ +2¹⁹/₄₂)×3-64,5÷6+4²/₇×2,1+1,3+4¹/₆=
18¹⁷³/₂₁₀
1)
³¹/₁₂ +¹⁰¹/₄₂ = ³¹ˣ⁷/₈₄+¹⁰³ˣ²/₈₄= ²¹⁷/₈₄+²⁰⁶/₈₄ = ²¹⁷⁺²⁰⁶/₈₄ = ⁴²³/₈₄
2) ⁴²³/₈₄×3 = ⁴²³ˣ³/₈₄ = ⁴²³/₂₈
3) 64,5÷6 = 10,75
4) ⁴²³/₂₈-10,75=⁴²³/₂₈-¹⁰⁷⁵/₁₀₀ = ⁴²³/₂₈-⁴³/₄ = ⁴²³/₂₈-⁴³ˣ⁷/₂₈=⁴²³/₂₈-³⁰¹/₂₈= ¹²²/₂₈ =⁶¹/₁₄=4⁵/₁₄
5) 4²/₇×2,1 = ³⁰/₇ײ¹/₁₀= ³⁰ˣ²¹/₇ₓ₁₀ = ⁹/₁ = 9
6) 4⁵/₁₄+9 = 13⁵/₁₄
7) 13⁵/₁₄ +1,3 = 13⁵/₁₄ +¹³/₁₀=¹⁸⁷/₁₄ +¹³/₁₀=¹⁸⁷ˣ⁵/₇₀+¹³ˣ⁷/₇₀=⁹³⁵/₇₀+⁹¹/₇₀=⁹³⁵⁺⁹¹/₇₀=¹⁰²⁶/₇₀
8) ¹⁰²⁶/₇₀ + 4¹/₆=⁵¹³/₃₅ + ²⁵/₆= ⁵¹³ˣ⁶/₂₁₀ + ²⁵ˣ³⁵/₂₁₀= ³⁰⁷⁸/₂₁₀+⁸⁷⁵/₂₁₀=³⁹⁵³/₂₁₀= 18¹⁷³/₂₁₀
