Answer:

-

Step-by-step explanation:

-6/12+1/10+(-3/6)+4/20

= -1/2+1/10+(-1/2)+1/5

= -1/4 + 3/10

= 2/40

= 1/20

=0.05

Answer 2

Answer:

$\frac{ - 6}{12} + \frac{1}{10} + ( \frac{ - 3}{6} ) + \frac{4}{20}$

$= ( \frac{ - 6 \times 5}{12 \times 5}) + ( \frac{1 \times 6}{10 \times 6}) + (\frac{ - 3 \times 10}{6 \times 10} ) + ( \frac{4 \times 3}{20 \times 3} )$

$= \frac{ - 30 + 6 - 30 + 12}{60}$

$\frac{ - 60 + 18}{60}$

$= 18$
