(2,29 - 1/4) : 1/50 + (1 4/5 + 0,75) : 3 = 102,85.
1) 2,29 - 1/4 = 2,29 - 0,25 = 2,04
2) 2,04 : 1/50 = 2,04 : 0,02 = 204 : 2 = 102
- - - - -
3) 1 4/5 + 0,75 = 1,8 + 0,75 = 2,55
4) 2,55 : 3 = 0,85
- - - - -
5) 102 + 0,85 = 102,85.
Пояснения:
1/4 = 25/100 = 0,25 - доп.множ. 25
1/50 = 2/100 = 0,02 - доп.множ. 2
