a.)1.37.38-1=36.38

2)275-1=274

3)36.38:274=0.13

4)0.13*4=0.52

b.)1)24+7.6=31.6

2)8.9-31.6=-22.7

3)-22.7:5=-4.54

4)-4.54+9=4.46

5)42-4=38

6)38-62=-24

7)4.46:5=0.49

8)0.4(-24)=24.49

9)24.49*100=2449

c.)1)24:22=1.09

2)21.09=25.09

3)2.181+10=12.181

4)12.181-25.09=-12.909

5)6+2=8

6)8*(-12.909)=-103.272

7)3+(-103.272)=+100.272

8)10*(-103.272)=-1032.72
