Answer 1

$a) \frac{12 {a}^{5} {b}^{3} }{18ab} = \frac{6ab \times 2 {a}^{4} {b}^{2} }{6ab \times 3} = \frac{2 {a}^{4} {b}^{2}}{3} = \frac{2}{3} {a}^{4} {b}^{2}.$

$b) \frac{16x(x - y)}{24y(x - y)} = \frac{8(x - y) \times 2x}{8(x - y) \times 3y} = \frac{2x}{3y}.$

$c) \frac{{x}^{2} + x}{{x}^{2} } = \frac{{x}^{2}(1 + \frac{1}{x})}{ {x}^{2} } = 1 + \frac{1}{x} = \frac{x + 1}{x}.$
