a)
[tex] \frac{2x \times ( - 3y)}{ - 2} = \frac{ - 6xy}{ - 2} = 3xy[/tex]
b)
[tex] \frac{6p \times 2q}{4} = \frac{12pq}{4} = 3pq[/tex]
c)
[tex] \frac{0.5ab \times (- a)}{ \frac{1}{4} } = -0.5 {a}^{2} b \div \frac{1}{4} = - 2 {a}^{2} b[/tex]
d)
[tex] \frac{2y \times 3ty \times 0.6t}{0.1} = \frac{6t {y}^{2} \times 0.6t }{0.1} = \frac{3.6 {t}^{2} {y}^{2} }{0.1} = 36 {t}^{2} {y}^{2} [/tex]
