If you multiply by a number bigger than 1 then then answer is bigger than the original.

eg

4*1.5 = 6 which is bigger than 4

also

An enlargement using a negative scale factor is similar to an enlargement using a positive scale factor, but this time the image is on the other side of the centre of enlargement, and it is upside down.

SO is this enough infromation for you to answer your own question?

Contractions are smaller by the way.
