Question

Find the sum 4/7+2/-3+5/21+-8/9​

Answer 1

Answer:

$\frac{4}{7} + \frac{2}{ - 3} + \frac{5}{21} + \frac{ - 8}{9}$

$\frac{4}{7} \times \frac{3}{3} + \frac{2}{ - 3} \times \frac{ - 7}{ - 7} + \frac{5}{21} + \frac{ - 8}{9}$

$= ( \frac{12 - 14 + 5}{21}) + \frac{ - 8}{9}$

$= ( \frac{3}{21} ) + \frac{ - 8}{9}$

$= ( \frac{1}{7} + \frac{ - 8}{9} )$

$= \frac{ 9 -56 }{72}$

$= \frac{ 47 }{72}$
