Question

1)0,014/0,56=          2)24,1248/0,048=      3) (x+19,64)*0,18=144       4)0,8-(x-0,326)=0,495

Answer 1

1) 0.025
2) 502.6
3)2.047

Answer 2

1)0,014/0,56= 14/1000 : 560/1000 =14/560 =7/280 =1/40 = (1000/40):1000 =25/1000 = 0,025
2)24,1248/0,048= 241248/10000 : 480/10000=241248/480= =(241248/48):10=5026:10=502,6
3) (x+19,64)*0,18=144
x+19,64=144/0,18
x=144/0,18-19,64= (144:18)*100-19,64=800-19,64=780,36
4)0,8-(x-0,326)=0,495
  -(x-0,326)=0,495-0,8=−0,305
     x-0,326=0,305
    x=0,305+0,326=0,631
