Question

Perform the indicated operation of multiplication or division on the rational and and simplify.

Answer 1

Consider the given expression,

`(12)/(5y^3)/(18)/(y^3)`

Consider the analogy,

`(a)/(b)/(c)/(d)=(a)/(b)*(d)/(c)`

Then the given expression becomes,

`\begin{gathered} =(12)/(5y^3)*(y^3)/(18) \\ =(2)/(5)*(1)/(3) \\ =(2)/(15) \end{gathered}`

Thus, the simplification of the expression gives 2/15.
