1) (3a^2)/b : a/b^2 = (3a^2 •〖 b〗^2)/(b • a) = 3ab/1 = 3ab;
2) –3p/c^3 : (15p^2)/c^2 = –(3p •〖 c〗^2 )/(c^3 • 15p^2 ) = –1/5pc;
3) 4p/5c : (8p^2)/(15c^3 ) = (4p • 15c^3)/(5c • 8p^2 ) = (3c^2)/2p;
4) (15m^3)/c : (–10m2) = (15m^3 • 1)/(c • (-10m^2)) = –3m/2c;
5) –(2a^2)/b : (–8a2) = (2a^2 • 1)/(b • 8a^2 ) = 1/4b;
6) –12a2bc : 4ab/m = (-12a^2 bc • m)/4ab = –3acm/1 = –3acm.
