(A)

we are given

(-1.15) x 3.2

Since, sign of 1.15 is negative

and sign of 3.2 is positive

so, we put negative sign in front

(-1.15)*(3.2)=-(1.15*3.2)

now, we can multiply them

and we get

(-1.15)*(3.2)=-3.68.............Answer

(B)

Suppose, we are given product of two numbers 'a' and 'b'

so, we use this property

case-1: When both positive , then we put positive in front

a*b=+(a*b)

case-2: When both negative  , then we put positive in front

-a*-b=+(a*b)

case-3: When first is  negative and second is positive   , then we put negative  in front

-a*b=-(a*b)


case-4: When first is  positive and second is negative    , then we put negative  in front

a*-b=-(a*b)
