Solve the Equation: 3x Divided by 2t and 4z

First let's rewrite the expression as a fraction:

$\frac{3x}{2t\times4z}=$

We should note that since there is only a multiplication operation in the numerator of the fraction, we will multiply the coefficients together:

$\frac{3x}{2\times4\times t\times z}=\frac{3x}{8tz}$
