c)= 39

d)= -26

explicación paso a paso:

a) -7.7-3.5+14:2-9.4+7.(-3)=

-49-3.5+14:2-9.4+7.(-3)=

-49-15+7-36+7.(-3)=

-64+7-36+(-21 )=

-57-36+(-21 )=

-93+(-21 )=

-93-21= -114

b)-9.7+40:8-36:(-6)+11.3+10.(-3)=

-63+5-(-6)+33+(-30)=

-63+5+6+33-30=

-58+6+33-30=

-52+33-30=

-19-30= -49

c) 25.3+12.(-4)+(-3).(-5)-(9):3=

75+(-48)-3.(-5)-9:3=

75-48+15-3=

27+15-3=

42-3= 39

d) 8.(-5)+49:(-7)-(-3).6+12:4=

-40+(-7 )+3.6+3=

-40-7+18+3=

-47+18+3=

-29+3= -26
