$\frac{12xyz}{8x}=\frac{4(3)(x)(y)(z)}{4(2)(x)}$

Cancel out the terms that are common to the numerator and denominator. That will give you the answer.

I hope this helps

since 12/8 = 3/2 and y/y = 1, we have: $\frac {12xyz}{8y} = \frac {\not 1 \not 2^3x \not yz}{\not 8_2 \not y} = \frac {3xz}{2}$

the principle behind this is "canceling common factors, which really falls back on the rule: $\frac {x^a}{x^b} = x^{a - b}$

so $\frac {12xyz}{8y} = \frac {12}8 \cdot x \cdot yy \cdot z = \frac 32 \cdot x \cdot 1 \cdot z = \frac {3xz}{2}$ since $\frac yy = \frac {y^1}{y^1} = y^{1 - 1} = y^0 = 1$

It does somewhat but I still don't completly understand so I can't figure out the answer.

Thanks, Niles Nimmo

Thank You very much

Its exactly what I was looking for
