А) 7²/₃ × 2¹/₄ = ²³/₃ × ⁹/₄ = ²³ˣ⁹/₃ₓ₄ = ²³ˣ³/₄ = ⁶⁹/₄ = 17,25
Б) ⁷/₉ × 4¹/₂ = ⁷/₉ × ⁹/₂ = ⁷ˣ⁹/₉ₓ₂ = ⁷/₂ = 3¹/₂ = 3,5
В) 3²/₇ × 8 = ²³/₇ × ⁸/₁ = ²³ˣ⁸/₇ₓ₁ = ¹⁸⁴/₇ = 26²/₇
Г) 21¹/₉ × 9 = 21¹/₉ × 9 = ¹⁹⁰/₉ × ⁹/₁ = ¹⁹⁰ˣ⁹/₉ₓ₁ = 190
Д) ³/₇ × 3¹/₃ = ³/₇ × ¹⁰/₃ = ³ˣ¹⁰/₇ₓ₃ = ¹⁰/₇ = 1³/₇
Е) 5²/₅ × 1¹/₉ = ²⁷/₅ × ¹⁰/₉ = ²⁷ˣ¹⁰/₅ₓ₉ = ³ˣ²/₁ₓ₁ = ⁶/₁ = 6
