b. -21/20
c. -7/6
d. -1/2
e. 5/6
f. -24
g. -5/42
Explicación paso a paso:
a. -1/2 + ? = -1/2
? = -1/2 + 1/2
? = 0
__________________
B. 3/4 + ? = -3/10
? = -3/10 - 3/4
? = -6/20 -15/20
? = -21/20
C. ? + 1/6 = -1
? = -1 - 1/6
? = -6/6 -1/6
? = -7/6
D. ? + ? = -1
? = -1/2
E. 3/5× ? = 1/2
? = 1/2 : 3/5
? = 1/2 * 5/3
? = 5/6
F. 1/8 × ? = -3
? = -3 : 1/8
? = -24
G. ? × -7 = 5/6
? = 5/6 : (-7)
? = 5/6 * (-1/7)
? = -5/42
