-\dfrac{1}{6} \times \left(-\dfrac{9}{7}\right)− 6 1 ​ ×(− 7 9 ​ )minus, start fraction, 1, divided by, 6, end fraction, times,
sergey [27]

Answer:

  \dfrac{3}{14}

Step-by-step explanation:

The even number of minus signs means the product will be positive. A factor of 3 can be removed to simplify the product. As usual, the numerator of the product is the product of numerators, and the denominator of the product is the product of denominators.

  -\dfrac{1}{6} \times \left(-\dfrac{9}{7}\right)=\dfrac{1\cdot 9}{6\cdot 7}=\dfrac{3\cdot 3}{3\cdot 14}=\boxed{\dfrac{3}{14}}
