12/18 (cause 6 & 6 is 12 out of 18) that equals

2/3

18 marbles in total.

12 aren’t white.

12/18 marbles not white.

2/3 marbles not white.

well you have 18 marbles
12 of which or not white
so divide 12 into 18
12/18=2/3 or 66%

You have 12 non-white marbles out of 18, so the fraction of non-white marbles is 12 / 18 or 2 / 3.
