Answer:
[see below]
Step-by-step explanation:
[tex]\frac{1}{90}*-\frac{1}{3}\\\\\frac{1*-1}{90*3}\\\\\frac{-1}{270}\\\\\boxed{-\frac{1}{270}}[/tex]
If a number gets multiplied by it's reciprocal, the product would be one.
[tex]\frac{x}{y}*\frac{y}{x}=1\\\\-\frac{1}{270}*-\frac{270}{1}= 1[/tex]
The reciprocal of the product of the equation is [tex]-\frac{270}{1}[/tex].
Hope this helps.
