#### Answer

$8/3 \times x\times y\times z$

#### Work Step by Step

We know that we need an expression with x, y, and z in it. To make it simpler, we will multiply the three numbers together. Because $x\times y\times z$ equals -6 right now, we must multiply -6 by a number to get -16. We know that -6 times 8/3 is -16, so we get the expression: $8/3 \times x\times y\times z$.
