Question 209684
Can someone help me with this problem please? Build each rational expression into an equivalent rational expression with the indicated denominator 
-7yt/3x = ?/18xyt
---
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
===========================
Cheers,
Stan H.
