Question

Rozpisz i Oblicz:
-5,65 + ( -2,08) - 1,35 =
6,51 + ( -2,775) - 11,125 =
- 10/9 + ( - 1/6) + 9 3/4 - (- 6,25) =
-9,3 - ( - 12 1/5) - 72,8 - ( -13,002)) =

Answer 1

-5,65+(-2,08)-1,35=-5,65-2,08-1,35=-9,08

6,51+(-2,775)-11,125=6,51-2,775-11,125=6,51-13,9=-7,39

-10/9+(-1/6)+9 i 3/4-(-6,25)=-10/9-1/6+39/4+625/100=-10/9-1/6+39/4+25/4=

=-40/36-6/36+351/36+225/36=-46/36+576/36=530/36=14 i 26/36=14 i 13/18

-9,3-(-12 i 1/5)-72,8-(-13,002)=-9,3+61/5-72,8+13,002=

=-9,3+12,2-72,8+13,002=-82,1+25,202=56,898
