Пошаговое объяснение:
а) 1/24 * 18= 18/24= (3*6)/(4*6)=3/4
б) 35 * 3/70 = (35*3)/(35*2)=3/2=1 1/2
в)5/16 * 12= (5*3*4)/(4*4)=15/4=3 3/4
г) 144* 15/48= (48*3*15)/48=3*15=45
д) 25* 3/5 = (5*5*3)/5=5*3=15
е) 17/21 * 6/51 * 14=17/(7*3) * (2*3)/(17*3)* (7*2)=(2*2)/3=4/3= 1 1/3
ж) 45/77 * 49/81= (9*5)/(11*7) * (7*7)/(9*9)=(5*7)/(11*9)=35/99
з) 23/64 * 16/46 * 32= 23/(8*8) * (2*8)/(2*23) * (8*4)=4
