$\huge\bold{ \frac{4}{7} \: + ( - \frac{8}{9}) \: + ( \frac{ - 5}{21} ) \: + \frac{1}{3} }$

$\huge\bold{ \frac{4}{7} \: - \: \frac{ - 8}{9} \: \: - \: \frac{ 5}{21} \: + \: \frac{1}{3} \: }$

$\huge\bold{ \frac{9 \: - \: 56 \: - \: 15 \: + \: 21 \: }{63} \: }$

$\huge\bold{ \frac{ - 41}{63} }$

Answer 2

Answer:

-2/9

Step-by-step explanation:

4/7+(-8/9)+(-5/21)+1/3 = 4/7 - 8/9 - 5/21 + 1/3

= 4/7 - 5/21 + 1/3 - 8/9

= [(4(3)-5)/21] + [(1(3)-8)/9]

= [(12-5)/21] + [(3-8)/9]

= [7/21] + [-5/9]

= [1/3] - 5/9

= 1/3-5/9

= (1(3)-5)/9

= (3-5)/9

= (-2)/9

= - 2/9
