Question

Can anyone prove this?
If x>y and z>0, then xz>yz

Answer 1

Basically, since z > 0 and occurs on both sides, you can treat z as a constant (since z is on both sides and are the same value)
if you were to divide both sides by z it would just leave the equation x(1)>y(1)
since the ratio is just states to the original x > y which is always true.
Therefore, xz>yz.
Does that help?

Answer 2

YES! Like seriously, you're my new best friend. Do you do proofs often?

Answer 3

I don't do them often, but I can relate general math in a way that makes sense.

Answer 4

Well thank you again for your help.
