Question

2/3+3/7+(-6/7)+(-13/7)​

Answer 1

Answer:

-34/21

Step-by-step explanation:

2/3 + 3/7 + (-6/7) + (-13/7)

= 2/3  + 3/7 - (6/7 + 13/7)

= 2/3  + 3/7 - (19/7)

= 2/3 + (3/7 - 19/7)

= 2/3 + (-16/7)

= 2/3 - 16/7

= 14/21 - 48/21

= -34/21

= or -1.619

Answer 2

$\frac{2}{3} + \frac{3}{7} + ( \frac{ - 6}{7} ) + ( \frac{ - 13}{7} )$

$\frac{5}{10} + ( \frac{ - 6}{7} + \frac{ - 13}{7} )$

$\frac{5}{10} + ( \frac{19}{14} )$

$\frac{24}{24}$

$\frac{12}{12}$

$\frac{6}{6}$

$\frac{3}{3}$

$\frac{1}{1}$
