a) 1,75-(+3,6)+(-4,21)
b) $-\frac{2}{3}$ - $(-\frac{1}{2} )$ - $(+\frac{1}{6})$
c) 1+$\frac{1}{2} -\frac{2}{4} +\frac{5}{6}$
d) -33,44-(-11,22)
e) +0,88-(-12)-11,04

Answer 1

Resposta
a) 1,75-(+3,6)+(-4,21)
1,75-3,6-4,21
1,75-7,81=-6,06

b)-2/3-(-1/2)-(+1/6)
-2/3+1/2-1/6
-4-1/6+1/2
-5/6+1/2
-5+3/6
-2/6

c)1+1/2-2/4+5/6
1+6-6+10/6
1+10/6
6+10/6= 16/6

d)-33,44-(-11,22)
-33,44+11,22=-22,22

e)+0,88-(-12)-11,04
+0,88+12-11,04
12,88-11,04=1,84
