a)-52 : __ = -13 ; b)-144 : __ = -6

c) 76 : __ = -2 ; ; d) -44 : __ = +11

e)-216 : __ = +4 ; f) __ : ( -3) = -13

g) __ : ( -7 ) = -15 ; h) __ : (+6 ) = -12​

Answer 1

Răspuns:

Explicație pas cu pas:

a)

- 52 : a = - 13

a = ( - 52) : ( - 13 )

a = 4

- 52 : 4 = - 13

_______________

b)

- 144 : b = - 6

b = ( - 144 ) : ( - 6 )

b = 24

- 144 : 24 = - 6

________________

c)

76 : c = - 2

c = 76 : ( - 2 )

c = - 38

76 : ( - 38 ) = 2

_______________

d)

- 44 : d = + 11

d = ( - 44 ) : 11

d = - 4

V   ( - 44 ) : ( -4) = 11

_________________

e)

- 216 : e = + 4

e = ( - 216 ) : 4

e = - 54

- 216 : ( - 54 ) = 4

______________

f)

f : ( - 3 ) = - 13

f = ( - 13 ) x ( - 3 )

f = 39

39 : ( - 3 ) = - 13

_____________

g)

g : ( - 7 ) = - 15

g = ( - 15 ) x ( - 7 )

g = + 105

105 : ( - 7 ) = - 15

______________

h)

h : ( + 6 ) = - 12

h = ( - 12 ) x 6

h = - 72

- 72 : 6 = - 12
