a) (-13)* 1,5 + 2,5 = -17
b) (-3)+ (-4)+ (-13) = -20
c) (-2)* 4,5 : 1,5 = -6
d) (-12)+ 2,5/(-17) = -12 - 5/34 = -12/1 - 5/34 = -408/34 - 5/34 = -413/34
a) (-13)* 1,5- ..?.. = -17
-19,5 - ..?.. = -17
-19,5 -(- 2,5) = -17
b) (-3)+ (-4)+ (-13)= ..?..
(-3)+ (-4)+ (-13) = -20
c) (-2)* 4,5 : 1,5= ..?..
-9 : 1,5 = -6
d)(-12)+ 2,5/ .(-2,5).. = ..?..
-12 - 1 = -13
