(8/7) ÷ (-3/4)=

(-3/7)(____)=12/21​

Answer 1

Respuesta:

1: -63÷7=-9

2: (5)(-3)(2)=-30

3: (-3/4)(4/7)=-3/7

4: (8/7)÷(-3/4)=-6/7

5: (-3/7)(-4/3)=12/21

Explicación paso a paso:

1: X÷7=-9. -63÷7=-9

X=(-9)(7)

X=-63

2: (5)(X)(2)=-30. (5)(-3)(2)=-30

5x=-30÷2

5x=-15

X=-15÷5

X=-3

3: (-3/4)(4/7)=X. (-3/4)(4/7)=-3/7

X=(-3/4)(4/7)

X=-3/7

4: (8/7)÷(-3/4)=X. (8/7)÷(-3/4)=-6/7

X=(8/7)÷(-3/4)

X=-6/7

5: (-3/7)(X)=12/21. (-3/7)(-4/3)=12/21

X=(12/21)÷(-3/7)

X= -4/3
