Answer:

See the attached image

Explanation:

The first step is the production of the carboanion in the $CH_3Li$ compound. We will get the negative charge on the methyl group and the positive charge in the Li atom.

Then the carboanion can attack the acetone. The double bond of the oxo group would delocalized upon the oxygen, generating a positive charge in the carbon that can be attacked by the carboanion formaiting a new C-C bond.
