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

1.	4/7 + -8/9 + -5/21 + 1/3
Answer» 4/7 + -8/9 + -5/21 + 1/3 = - 0.16 $= \frac{4}{7} + \frac{ - 8}{9} + \frac{ - 5}{21} + \frac{1}{3} \\ = 0.57 + ( - 0.8) + ( - 0.23) + 0.3 \\ = 0.57 - 0.8 - 0.23 + 0.3 \\ = - 0.8 - 0.23 + 0.57 + 0.3 \\ = - 1.03 + 0.83 \\ = - 0.16$

Answer»

4/7 + -8/9 + -5/21 + 1/3 = - 0.16

$= \frac{4}{7} + \frac{ - 8}{9} + \frac{ - 5}{21} + \frac{1}{3} \\ = 0.57 + ( - 0.8) + ( - 0.23) + 0.3 \\ = 0.57 - 0.8 - 0.23 + 0.3 \\ = - 0.8 - 0.23 + 0.57 + 0.3 \\ = - 1.03 + 0.83 \\ = - 0.16$
