Question

Descompuneti in factori termenii fiecarui raport si apoi simplificati:
a)$\frac{2a-2b}{4a}$
b)$\frac{4x-4y}{8a+8b}$
c)$\frac{4x+4y}{12x+12y}$
d)$\frac{ab}{a-ab}$

Answer 1

[tex]a)...\;\;...=\frac{2(a-b)}{4a}=\frac{a-b}{2a}\;;\\ b)...\;\;...=\frac{4(x-y}{8(a+b)}=\frac{x-y}{2(a+b)}\;;\\ c)...\;\;...=\frac{4x+4y}{3(4x+4y)}=1/3\;;\\ d)...\;\;...=\frac{ab}{a(1-b)}=\frac{b}{1-b}\;\\[/tex]
