You can put this solution on YOUR website! Can someone help me with this problem please? Build each rational expression into an equivalent rational expression with the indicated denominator

Divide 3x into 18xyt = 6yt
---
? = 6yt
===============================
Find the LCD for the given rational expressions, and convert
each rational expression into an equivalent rational expression
with the LCD as the denominator
4/(x - y), 5x/(2y - 2x)
---
Factor:
4/(x-y) ; 5x[-2(x-y)]
-------------------
LCD = -2(x-y)
----
(4*-2)/LCD ; 5x/LCD
===========================
