2)(56,42:1,4-1,536:0,32)*2,1-6,8=
3)120-(7,0056:0,072+14,62)=
4)(4*1,125-4,5)*6,84+(3,54+1,824):0,76=

Answer 1

3,12 / 0,6 + 24 / 0,75 – 8 / 25 + 28 / 0,35 = 116,88
3,12/0,6=5,2
24/0,75=32
8/25=0,32
28/0,35=80
5,2+32=37,2
37,2-0,32=36,88
36,88+80=116,88
(56,42 / 1,4 – 1,536 / 0,32) * 2,1 – 6,8 = 67,75
56,42/1,4=40,3
1,536/0,32=4,8
40,3-4,8=35,5
35,5*2,1=74,55
74,55-6,8=67,75
120 – (7,0056 / 0,072 + 14,62) = 8,08
7,0056/0,072=97,3
97,3+14,62=111,92
120-111,92=8,08
(4 * 1,125 – 4,5) * 6,84 + (3,54 + 1,824) / 0,76 = 7,057894737
4*1,125=4,5
3,54+1,824=5,364
4,5-4,5=0
0*6,84=0
5,364/0,76=7,057894737
0+7,057894737=7,057894737
