Question

+ 3 by 7 plus minus 1 by 6​

Answer 1

Answer:

$- \frac{5}{7} + \frac{1}{12} - \ \frac{1}{10} + \frac{3}{7} - \frac{1}{6} \\ \frac{1}{12} + \frac{3}{7} - \frac{5}{7} - \frac{1}{10} - \frac{1}{6} \\ \frac{7 + 36}{84} - \frac{150 - 21 - 35}{210} \\ \frac{43}{84} - \frac{206}{210} = \frac{86 - 1030}{42} = \frac{ - 944}{42} = - 22.47$
