Answer 1

1) 3,14:0,6+24:0,75-3:25+28:3,25 =
=5,2+32-0,12+8,6=
=45,68


2)120-7,0056:0,072+14,62=
=120-97,3+14,62=
=37,32


3)(41,125-4,5)*6,84+(3,54+1,324):0,76=
=36,6*6,84+4,9/0,76=
=250,3+6,4=
=256,7


4)132-5х=3,192
  -5х=3,192-132
  -5х=-128,808
  х=-128,808/(-5)
  х=25,76


5)7х+5х-0,28=9,1
  12х=9,38
  х=9,38/12
  х=0,78

Answer 2

1)
3,14:0,6+24:0,75-3:25+28:3,25 = 314/100*10/6 + 24*100/75 - 3*1/25 + +28*100/325 = 157/30 + 32 - 3/25 + 112/13 = 5 7/30 + 32 - 3/25 + 8 8/13 = 
= (5 + 32 + 8) + (7/30 - 3/25 + 8/13) = 45 + (455/1950 - 234/1950 + +1200/1950) = 45 + 1421/1950 = 45 1421/1950,

2)
120-7,0056:0,072+14,62 = 120 - 97,3 + 14,62 = 37,32,

3)
(41,125-4,5)*6,84+(3,54+1,324):0,76 = 36,625*6,84 + 4,864:0,76 =
 = 250,515 +  6,4 = 256,915,

4)
132-5х=3,192,
-5х = 3,192 - 132,
-5х = -128,808,
х = 25,7616,

5)
7х+5х-0,28=9,1,
12х = 9,1+0,28,
12х = 9,38,
х = 938/100 : 12 = 938/100 * 1/12,
х = 469/600
