Пошаговое объяснение:
1)2/3a и 1/6b = 4b/6ab и a/6ab; 2)3/4a и 1/6с = 9c/12ac и 2a/12ac; 3) 1/6a² и 1/8ab = 4b/6a²b и 3a/24a²b; 4) 1/15bc и 1/25b² = 5b/75b²c и 3c/75b²c; 5) 1/3(a + b)⁴ и 1/2(a + b) = 2/ 6(a + b)⁴ и 3(a + b)³/6(a + b)⁴; 6) 1/3(x + y)⁵ и 1/5(x + y) = 5/15(x + y)⁵ и 3(x + y)⁴/ 15(x + y)⁵ ; 7) 1/20(x - y)² и 1/15(x - y)³ = 3(x - y)/60(x - y)³ и 4/60(x - y)³; 8) 1/12(a - b)⁴ и 1/8(a - b)³ = 2/24(a - b)⁴ и 3(a - b)/24(a - b)⁴
