The computation shows that the value of the expression given will be -1 14/15.

How to compute the value?

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.
