Verified answer

Пошаговое объяснение:

9 19/100 = (9*100 + 19)/100 = (900 + 19)/100 = 919/100

919/100 = 919 : 100 = 9,19

7 3/10 = (7*10 + 3)/10 = (70 + 3)/10 = 73/10

73/10 = 73 : 10 = 7,3

29 9/1000 = (29*1000 + 9)/1000 =

(29000 + 9)/1000 = 29009/1000

29009/1000 = 29009 : 1000 = 29,009

1 239/10000 = (1*10000 + 239)/10000 =

(10000 + 239)/10000 = 10239/10000 = 1,0239
