c) -3.242

d) 6.4

Step-by-step explanation:

a)

$\frac{7}{70} \\ \frac{7 \div 7}{70 \div 7} \\ \frac{1}{10} \\ 0.1$

b)

$\frac{ - 36}{180} \\ \frac{ - 36 \div 36}{180 \div 36} \\ \frac{ - 1}{5} \\ - 0.2$

c)

$\frac{132}{ - 428} \\ \frac{ - 132}{428} \\ \frac{ - 132 \div 4}{428 \div 4} \\ \frac{ - 33}{107} \\ - 3.242$
