Answer 1

$1)\frac{6a^{2}b }{8ab^{3} }=\frac{3a}{4b^{2} }$

$2) \frac{12x^{3} y^{6} }{18x^{4}y^{2} } =\frac{2y^{4} }{3x}$

$3) \frac{30a^{6}b^{4}c^{7} }{35a^{5}b^{7}c^{9} } =\frac{6a}{7b^{3}c^{2} }$

$4) -\frac{48x^{3}y^{5}g^{4} }{56xy^{3}g^{9} } =-\frac{6x^{2} y^{2} }{7g^{5} }$

$5) \frac{6x+6y}{12x+12y}=\frac{6(x+y)}{12(x+y)} =\frac{6}{12} = \frac{1}{2} =0.5$

$6) \frac{x^{2} -y^{2} }{2x-2y}=\frac{(x-y)(x+y)}{2(x-y)} =\frac{x+y}{2}$

$7) \frac{x^{2} +2x}{3x^{2} +6x}=\frac{x(x+2)}{3x(x+2)} =\frac{x}{3x}=\frac{1}{3}$
