Question

-2/3+1/2+-7/9+7/8 please tell the answer​

Answer 1

Answer:

$\frac{ - 2}{3} + \frac{1}{2} + \frac{ - 7}{9} + \frac{7}{8} \\ \\ \\ = \frac{2 \times - 2 + 3}{6} = \frac{ - 4 + 3}{6} = \frac{ - 1}{6} \\ \\ \frac{ - 7}{9} + \frac{7}{8} = \frac{ - 7 \times 8 + 7 \times 9}{9 \times 8} = \frac{ - 56 + 63}{72} = \frac{7}{72} \\ \\ \frac{ - 1}{6} + \frac{7}{72} = \frac{ - 72 + 42}{432} = \frac{ - 30}{432} = \frac{ - 15}{216} = \frac{ - 5}{72}$
