Aclass of 30 is divided into 2 groups such that the size of the smaller group is 2/3 the size of the larger group. how large is the smaller group?

I kinda did a lil of this in my head so i might not be 100% correct, but i would say the bigger group is 20 and the smaller group is 10

d (5 x (-20)) * (100 x (0.7))
