Answer 1

Answer:

0

Step-by-step explanation:

$=\frac{-2}{5}* \frac{3}{7} *\frac{5}{6} +\frac{1}{7} \\\\=\frac{-30}{210} +\frac{1}{7}\\\\=\frac{-1}{7} +\frac{1}{7} \\\\=\frac{-1+1}{7} =\frac{0}{7} =0$

Answer 2

Answer:

0

$\frac{ - 2}{5} \times \frac{3}{7} \times \frac{5}{6} + \frac{1}{7}$

Step-by-step explanation:

$\frac{ - 2}{1} \times \frac{1}{7} \times \frac{1}{2} + \frac{1}{7}$

$\frac{ - 1}{1} \times \frac{1}{7} \times \frac{1}{1} + \frac{1}{7}$

$\frac{ - 1}{7} + \frac{1}{7}$

$\frac{ - 1 + 1}{7}$

$\frac{0}{7}$

$\frac{0}{7 } = 0$
