Answer 1

a)
1,35:1,5+5,4:1,35+0,4*0,2*(4,4-1,37)=
0,9+4+0,08*3,03=
0,9+4+0,2424=
4,9+0,2424=5,1424
b)
(3,5:10+11,37*10)-(0,057+3,218+3,218*2,5)=
=(0,35+113,7)-(0,057+3,218+8,045)=
=114,05-3226,102=-3112,052
c)
5,2*(4,5:0,9+1,25)*1,4-(2,123+5,873)*4=
5,2*(5+1,25)*1,4-7,996*4=
5,2*6,25*1,4-31,984=
32,5*1,4-31,984=
45,5-31,984=13,516
d)
10×3,05-25:10 la 2+4,15-3,7+10,03:0,1-1,5×5,7=
30,5-25:100+4,15-3,7+100,3-8,55=
30,5-0,25+4,15-3,7+100,3-8,55=
30,25+4,15-3,7+100,3-8,55=
34,4-3,7+100,3-8,55=
30,7+100,3-8,55=
131-8,55=122,45
