Answer 1

Resposta:

a)

$\frac{11.729 + 9.729}{12.729 + 18.729} = \frac{729.(11 + 9)}{729.(12 + 18)} = \frac{11 + 9}{12 + 18} = \frac{20}{30} = \frac{2}{3}$

b)

$\frac{24 {x}^{3} + 18 {x}^{2} }{6x} = \frac{6 {x}^{2} (4x + 3)}{6x} = x(4x + 3)$

c)

$\frac{5 {y}^{2} + y}{15y + 3} = \frac{y(5y + 1)}{3(5y + 1)} = \frac{y}{3}$

d)

$\frac{72.133 - 2.133}{1132.7 + 22.63} = \frac{133(72 - 2)}{1132.7 + 22.7.9} = \frac{133.70}{7(1132 + 198)} = \frac{133.10}{1132 + 198} = \frac{1330}{1330} = 1$
