Answer 2

`(-7)(-1.2)\leftrightarrow 8.4`

`(-2(1)/(2))(-2)\leftrightarrow 5`

`(2.5)(-2)\leftrightarrow -5`

`(7)(-1.2)\leftrightarrow -8.4`

Explanation:

Product rule of signs:

(+)(+) = (+)

(+)(-) = (-)

(-)(+) = (-)

(-)(-) = (+)

Using these signs simplify the given expression.

`(-7)(-1.2)=8.4`

It means (-7)(-1.2) is equivalent to 8.4.

`(-2(1)/(2))(-2)=(-(5)/(2))(-2)=5`

It means
`(-2(1)/(2))(-2)` is equivalent to 5.

`(2.5)(-2)=-5`

It means (2.5)(-2)- is equivalent to -5.

`(7)(-1.2)=-8.4`

It means (7)(-1.2) is equivalent to -8.4.
