Answer 1

1) 5,34:10+124:100
    5,34:10= 0,534
   124:100= 1,24
   0,534+1,24= 1,774.
2) 3,29:100+35,4:10
    3,29:100= 0,0329
    35,4:10= 3,54
    0,0329+3,54= 3,5729.
3) 178,3:1000+324:100=
    178,3:1000= 0,178
    324:100= 3,24
    0,178+3,24= 3,418.
4) 3254:1000-17,34:10
    3254:1000= 0,3254
    17,34:10= 1,734
    0,3254-1,734= -1,4086.
5) 0,32:100-5,2:10⁴
    0,32:100= 0,0032
    5,2:10000= 0,00052
    0,0032-0,00052= 0,00268.
6) 14,4:10-14,4:14,4:10000
    14,4:10= 1,44
    14,14:14,4= 1:10000= 0,0001
    1,44-0,0001= 1,4399.
