Given: The given expression is $\frac{-16}{21}\times\frac{14}{5}$. To do: We have to solve the given expression.  Solution: $\frac{-16}{21}\times\frac{14}{5}$ $=\frac{-16}{3}\times\frac{2}{5}$ [both 21 and 14 are factors of 7] $=\frac{-32}{15}$ Therefore,  $\frac{-16}{21}\times\frac{14}{5}$=$\frac{-32}{15}$.

The state of motion of an object depends on the velocity of the body. If an object's velocity is zero then the object's state of motion represents rest. If an object's velocity is not zero then the state of motion represents motion. An object at rest cannot change its state of ... Read More
