(5 7/18-1 16/45):I-2,2I/(I2,6I+5/16+I-0,15I):2 5/8 *1,4+0,8:I-0,02I/5 -6,2
1) 5 7/18-1 16/45=97/18-61/45=485/90-122/90=363/90
2) 363/90:I-2,2I=363/90:2,2=363/90:2 2/10=363/90:22/10=363/90:10/22=
=363/198
3) I2,6I+5/16=2,6+5/6=2 6/10+5/16=26/10+5/16=416/160+50/160=466/160
4) 466/160+I-0,15I=466/160+0,15=466/160+15/100=2330/800+120/800=
=2450/800
5) 2450/800:2 5/8=2450/800:21/8=2450/800:8/21=2450/2100
6) 363/198:2450/2100=766500/485100=7665/4851
7) 7665/4851*1,4=7665/4851*1 4/10=7665/4851*14/10=107310/48510=
=10731/4851
8) 0,8:I-0,02I=0,8:0,02=40
9) 40/5=8
10) 8-6,2=1,8
11) 10731/4851+1,8=10731/4851+1 8/10=10731/4851+18/10=
=194628/48510=4 588/48510=4 294/24255
