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