The computation shows that the value of the expression given will be -1 14/15.
Based on the information given, it should be noted that it's important to expand the variables given to get the value.
This will be illustrated as follow:
= (-1/5 × 3) - (12 × 1/3²)
= -3/5 - (12 × 1/9)
= -3/5 - (4/3)
= -9/15 - 20/15
= - 29/15 = -1 14/15
Therefore, the value of the expression given will be -1 14/15.
