Пошаговое объяснение:
б)(7/125)*(1000/343)=8/49
в)(5/4:15/8)/((5/6-3/4)*24/10)=(2/3)/((20/24-18/24)*24/10)=(2/3)/(2/24*24/10)=2/3:2/10=10/3
б)27/250:729/1000=27/250*1000/729=4/27
в) 1. (1344/100):98/5)=(1344/100)*(5/8)=168/20=84/10=8,4
2. 31/7+5/3=93/21+35/21=128/21
3. 128/21*21/10=128/10=12,8
4. 8,4:12,8=84/128=21/32
