Comment: They are easier if you look at "like parts".
----------------
120xy/10x^2y^7
= (120/10)(x/x^2)(y/y^7)
= 12/(xy^6)
-------------------
2x(14x+12)/2^2
= [2x(2(7x+6))]/4
= [4x(7x+6)]/4
= [x(7x+6)]
==============
(8k^-7)^4 = 8k^-28 = 8/k^28
------------------
22a^7b^7/11a^3b^-7
=(22/11)(a^7/a^3)(b^7/b^-7)
= 2a^4b^14
=============
