Пошаговое объяснение:
1) = -¹⁶/₂₅ + ²¹/₂₅ - ¹³/₂₇ + ⁴/₂₇ = ⁵/₂₅ - ⁹/₂₇ = ¹/₅ - ¹/₃ = ³/₁₅ - ⁵/₁₅ = -²/₁₅
2 ) = ¹⁴/₃ - ³⁸/₁₅ + ¹³/₅ = ⁷⁰/₁₅ - ³⁸/₁₅ + ³⁹/₁₅ = ⁷¹/₁₅ = 4¹¹/₁₅
3) = -0.76 - 2.34 + 0.55 + 9.2 = -3.1 + 9.75 = 6.65
4) ⁹/₁₄ + x - ³/₇ = ²³/₂₈
x = ²³/₂₈ - ⁹/₁₄ + ³/₇
x = ²³/₂₈ - ¹⁸/₂₈ + ¹²/₂₈
x = ¹⁷/₂₈
5) -24 - y = -16
-y = -16 + 24
-y = 8
y = -8.
