<PRE><B>Question 97946</B>
[(2x-6)/21] / [(5x-15)/12]


Invert and multiply:

[(2x-6)/21] * [12/(5x-15)]

Cancel the 3 factor common to numerator and denominator to get:

[(2x-6)/7] * [4/(5x-15)]

Factor to get:
[2(x-3)/7] * [4/(5(x-3)]

Cancel the (x-3) factor common to numerator and denominator to get:
[2/7]*[4/5]

= 8/35
