Dam naj za podpunkty a) i b) oraz c) d) e) f)
c) 2,66+ (-2 1/3)
d) 4.08 - (-3,275)
e) -2 1/3 - (-3.8)
f) -14,2-7,87

Answer 1

A)-3 i 1/9-(-4 i 1/17)=-28/9+69/17=-476/153+621/153=145/153

b)-2 i 14/15+0,2=-44/15+2/10=-44/10+1/5=-88/30+6/30=-82/30=-2 i 22/30=

=-2 i 11/15

c)2,66+(-2 i 1/3)=266/100-7/3=133/50-7/3=399/150-350/150=49/150

d)4,08-(-3,275)=4,08+3,275=7,355

e)-2 i 1/3-(-3,8)=-7/3+38/10=-70/30+114/30=44/30=1 i 14/30=1 i 7/15

f)-14,2-7,87=-22,07

Answer 2

D)4,08-(+3,275)=7,355
f)-14,2-7,87= -22,07
e)-2 1/3-(3,8)=-10,8
