\[\frac{ 5x^2y^3z^4 }{ 20x^3y^7z^4 } = \frac{ 5 }{ 20 }\times \frac{ x^2 }{ x^3 }\times \frac{ y^3 }{ y^7 }\times \frac{ z^4 }{ z^4}\]

use these steps for each one of those terms: \[\frac{ y^3 }{ y^7 }\] \[\frac{ z^4 }{ z^4 }\] and then put them all together

all the x terms, z terms cancel

not quite, the exponents on x and y should be negative, or you should put them in the denominator of your final answer like this \[\frac{ 1 }{ 4xy^4 }\] or \[\frac{ x ^{1}y ^{4} }{ 4 }\]

and yes \[\frac{ z ^{4} }{ z^4 } = 1 \] so it cancels

the x exponents cancel, why are you leaving them in? it's not a 2 on top, it's x^3

yes so x's would be x^1 or x^0

did you mean to put divide instead of subtract for x^3  x^3?
