214. Виконайте ділення: 1) 6x/5 : 3y/2 = 6x/5 • 2/3y = (bx •2)/(5 •3y) = 4x/5y; 2) 1/3x : 5/12x = 1/3x • 12x/5 = 12x/(3x •5) = 4/5; 3) 1/5a : 3/35ab = 1/5a • 35ab/3 = 35ab/(5a •3) = 7b/3; 4) 7a/2b : 14a/5 = 7a/2b • 5/14a = (7a •5)/(2b •14a) = 5/4b; 5) 1/(a^3 b^3 ) : 1/(a^2 b^2 ) = 1/(a^3 b^3 ) • (a^2 b^2)/1 = (a^2 b^2)/(a^3 b^3 ) = 1/ab; 6) (〖6x〗^2 y^4)/7 : (14xy^5)/35 = (〖6x〗^2 y^4)/7 • 35/(18xy^5 ) = (〖6x〗^2 y^4 •35)/(7 •18xy^5 ) = 5x/3y.
