75,6 : 1,5 – ((2,48 +1/8- 2,48 + 0,125) :1/4 - 4/7) ∙ 23 1/3 ∙ (1/6 - 0,026)=49
1.75,6/1,5=50,4
2.2,48+1/8=2,48+0,125=2,605
3.2,605-2,48=0,125
4.0,125+0,125=0,25
5.0,25/0,25=1
6.1-4/7=3/7
7.3/7*23 1/3=10
8.1/6-0,026=0,166-0,026=0,14
9.10*0,141=1,41
10.50,4-1,4=49
ну кажется так.............................................................
