Перетворіть на дріб вираз:

1) 9p • b/(6p^2 ) = (9p • b)/(6p^2 ) = 3b/2p;
2) (4m^3)/x^2 • x3 = (4m^3 x^3)/x^2 = (4m^3 x)/1 = 4m3x;
3) 9ab2 • (–5b/(3a^3 )) = –(9ab^(2 )• 5b)/(3a^3 ) = –(15b^3)/a^2 ;
4) –7ab3 • b^5/14a = –(7ab^3 • b^5)/14a = –b^8/2;
5) –4mn2 • 1/8mn = –(4mn^2 • 1)/8mn = –n/2;
6) –11a2b • (–5/(22a^3 b^2 )) = (11a^2 b • 5)/(22a^3 b^2 ) = 5/2ab.
