2)11/30:4,4=11/30:44/10=11*10/30*44=110/1320=1/12
3)4,35-1/12=87/20-1/12=261-5)/60=256/60=64/15=4.4/15
4)4.4/15=64/15  64/15*32/100=64/15*8/25=512/375
5)20-0,68=19,32

Answer 2

(4,35-(4/45 +5/18):4,4)*0,32
_______________________=0,3072
 (20-0,68):8,05+2 2/45.
по действия
4/45 +5/18=8/90+25/90=33/90=11/30
4,4=4 4/10=4 2/5=22/5
11/30:22/5=11/30*5/22=1/30*5/2=1/6*1/2=1/12
4,35=4 35/100=4 7/20
4 7/20-1/12=4 21/60-5/60=4 16/60=4 4/15=64/15
0,32=32/100=8/25
64/15*8/25=512/375

20-0,68=19,32
19,32:8,05=2,4=2 4/10=2 2/5
2 2/5+2 2/45=2 18/45+2 2/45=4 20/45=4 4/9=40/9

512/375:40/9=512/375*9/40=128/375*9/10=128/125*3/10=384/1250=0,3072
