Answer 1

A) -9.08
b) -7,39
c)-48 i 34/36
d)-82902/1000

Answer 2

a) -5,65 + ( -2,08) - 1,35 = -5,65-2,08-1,35= -9,08
b)6,51+(-2,775)-11,125 = 6,51-2,775-11,125 = -7,39
c)- 10/9 + (-1/6) + 9 3/4 -(-6,25) = - 10/9 - 1/6 + 39/4 + 25/4 = -40/36-6/36+351/36 +225/36 = 530/36 = 14  26/36 = 14 13/18
d)-9,3 - (-12 1/5 ) - (72,8-(-13,002)) = -9,3+12,2-85,802 = -82,902
