Yeah The C major scale is pretty much the same as a C major pentatonic scale. Just ommit the 4th and 7th note in the C major scale and you have the c maj pent.

Cmajor scale: c, d, e, f, g, a, b
c major pent: c, d, e, g, a

Same thing with the minor pent and minor scale, except you omit the 2nd and the 6th.
Aminor scale: a, b, c, d, e, f, g
a minor pent: a, c, d, e, g
