Question

simplify the following 4/7+-8/8+-5/21+1/3

Answer 1

$\frac{4}{7} + ( \frac{ - 8}{8} ) + ( \frac{ - 5}{21}) + \frac{1}{3}$
$\frac{4}{7} - 1 - \frac{5}{21} + \frac{1}{3}$
LCM Of 7,21,3 Is 21
$\frac{4(3) - 1(21 )- 5 + 1(7)}{21}$
$\frac{12 - 21 - 5 + 7}{21}$
$\frac{19 - 26}{21}$
$\frac{ - 7}{21}$
$\frac{ - 1}{3}$
$- 0.333333333$
