Answer 1

Resposta:

0.2abc

Explicação passo-a-passo:

$\frac{3.2a {}^{2} b {}^{2}c {}^{2} }{6abc + 10abc}$

Somar elementos similares : 6abc + 10abc= 16abc

=

$\frac{3.2a {}^{2} b {}^{2}c {}^{2} }{16abc}$

Eliminar o fator comum: a

=

$\frac{3.2ab {}^{2} c {}^{2} }{16bc}$

Eliminar o fator comum: b

=

$\frac{3.2abc {}^{2} }{16c}$

Eliminar o fator comum: c

=

$\frac{3.2abc}{16}$

Dividir:

$\frac{3.2}{16} = 0.2$
