34,17:1,7+(2si 3/4 +0,15):4/5-3-0,625=

Answer 1

   34,17:1,7+(2si 3/4 +0,15):4/5-3-0,625 = 
= 3417/100 : 17/10 + (11/4 + 15/100) : 4/5 - 3 - 625/1000 = 
= 3417/100 x 10/17 + (275/100 + 15/100) x 5/4 - 3 - 625/1000 = 
= 201/10 + 290/100 x 5/4 - 3 - 625/1000 = 
= 201/10 + 725/200 - 3 -625/1000 = 
= 40200/2000 + 7250/2000 - 6000/2000 - 1250/2000 = 
= 40200/2000 = 20100/1000 = 201/10 = 20,1
