Сократите дробь: а) 6a+6b _______ 9a в) ab-ad ______ abd д) ax-ay _______ ax+ay ж) axy+ax ________ ax+ axz

а) [latex] \frac{6a+6b}{9a} [/latex] = [latex] \frac{6(a+b)}{9a} [/latex] = [latex] \frac{2(a+b)}{3a} [/latex] в) [latex] \frac{ab-ad}{abd} [/latex] = [latex] \frac{a(b-d)}{abd} [/latex] = [latex]\frac{b-d}{bd} [/latex] д) [latex] \frac{ax-ay}{ax+ay} [/latex] = [latex] \frac{a(x-y)}{a(x+y)} [/latex] = [latex] \frac{x-y}{x+y} [/latex] ж) [latex] \frac{axy+ax}{ax+axz} [/latex] = [latex] \frac{ax(y+1)}{ax(1+z)} [/latex] = [latex] \frac{y+1}{1+z} [/latex]

а)(6а+6b)/9a=2(a+b)/3a=(2a+2b)/3a в)(ab-ad)/abd=a(b-d)/abd=b-d/bd д)(ax-ay)/(ax+ay)=a(x-y)/a(x+y)=(x-y)/(x+y) ж)(axy+ax)/(ax+axz)=(ax(y+1))/(ax(1+z))
