Which expression is equivalent to 4 over 9 (2n - 3)
AlexFokin [52]

Answer:

The result for this equation is \frac{8}{9}n - \frac{4}{3} .

Step-by-step explanation:

-Solve:

\frac{4}{9} (2n-3)

-Multiply 2n and -3 by \frac{4}{9} :

\frac{8}{9} + \frac{-12}{9}

-Reduce \frac{-12}{9} to the lowest term by extracting and canceling out 3:

\frac{8}{9}n - \frac{4}{3}

-So, the result is \frac{8}{9}n - \frac{4}{3} .
