Answer 2

Answer:

Let the required rational number be x

As per the condition,we get

x×5/2 +2/3=-7/12

5/2x+2/3=-7/12

5x/2=-7/12-2/3

{Transposing 2/3 to RHS}

5x/2=-7-8/12

5/2x=-15/12

x{-15/12÷5/2

{Transposing 5/3 to RHS}

x= -15/12×2/5=

3/6×2/5=-1/2

Hence,the required rational number is-1/2..
