1) a/(16m^2 ) • 12m = (a • 12m)/(16m^2 ) = 3a/4m;
2) a3 • (7x^3)/a^2 = (7x^3 a^3)/a^2 = (7x^3 a)/1 = 7x3a;
3) –7y/(4x^2 ) • 12xy2 = –(7y • 12xy^2)/(4x^2 ) = –(21y^3)/x;
4) 5cm4 • (–m/15c) = –(5cm^4• m)/15c = –m^5/3;
5) –5ab2 • (–1/10ab) = (5ab^2)/10ab = b/2;
6) 13c2d • 7/(26c^3 d^2 ) = (13c^2 d • 7)/(26c^3 d^2 ) = 7/2cd.
