Solve the equation 4/8y=8/3 for y

Solnce55 [7]

Answer:

$y = \frac{16}{3}$

Step-by-step explanation:

In order to solve for y, you need to isolate the y in the equation. Thus, to get rid of the $\frac{4}{8}$ multiplied by the y, multiply both sides by the reciprocal, $\frac{8}{4}$ . Then, reduce the fraction.
