Question

Запишите смешанное число в виде неправильной дроби 3 1/6 9 3/4 5 8/9 1 19/100

Answer 1

$1)\frac{6}{7x}=\frac{3}{7y}*\frac{2y}{x} \\ \\ 2)\frac{1}{3x}=\frac{2y}{9}*\frac{3}{2xy} \\ \\ 3)\frac{2}{y^2}=\frac{4}{xy}*\frac{x}{2y} \\ \\ 4)\frac{1}{y^3}=\frac{2}{xy}*\frac{x}{2y^2} \\ \\ 5)\frac{3}{a^2b}=\frac{3b}{a}*\frac{1}{ab^2} \\ \\ 6)\frac{7}{a^2b^3}=\frac{7}{a^3b}*\frac{a}{b^2}$

$7)\frac{4}{(a-b)^2}=\frac{4}{3a-3b}*\frac{3}{a-b} \\ \\ 8)\frac{12}{(a+b)^3}=\frac{4}{a+b}*\frac{3}{a^2+2ab+b^2} \\ \\ 9)\frac{1}{m^2-n^2}=\frac{1}{m-n}*\frac{1}{m+n} \\ \\ 10)\frac{2}{4m^2-9n^2}=\frac{1}{2m-3n}*\frac{2}{2m+3n} \\ \\ 11)\frac{3}{k^2-2k}=\frac{3}{4k}*\frac{4}{k-2} \\ \\ 12)\frac{1}{3k^2c-kc^2}=\frac{2}{3k-c}*\frac{1}{2kc}$
