Question

$- 1$
$- 1 \div 2 \times 4 \div 7 + 1 \div 2 - 3 \div 7 \times 1 \div 6$
​

Answer 1

Answer:

The value is $\frac{5}{14}$.

Step-by-step explanation:

Solve as follows:

$-1\div 2\times 4\div 7 + 1\div 2-3\div7\times 1\div6=-\frac{1}{2}\times\frac{4}{7}+\frac{1}{2}-\frac{3}{7}\times \frac{1}{6}\\=-\frac{1}{14}+\frac{1}{2}-\frac{1}{14}=-\frac{1}{7}+\frac{1}{2}\\=\frac{-2+7}{14}=\frac{5}{14}$

Thus, the value is $\frac{5}{14}$.
