1

Understand the problem

Solve the following problem:

(xyz):xyz=? (x\cdot y\cdot z):\frac{xy}{z}=\text{?}

2

Step-by-step solution

Let's flip the fraction to get a multiplication exercise:

(xyz)×zxy= (x\cdot y\cdot z)\times\frac{z}{xy}=

We'll add the multiplication exercise in parentheses to the numerator of the fraction:

x×y×z×zxy= \frac{x\times y\times z\times z}{xy}=

We'll simplify the x and y in the numerator and denominator of the fraction:

z×z1=z2 \frac{z\times z}{1}=z^2

3

Final Answer

z2 z^2
