2/3=0.66666 so two-thirds of a foot is 0.66666 feet which is about 8 inches.
There are 96 inches in 8 feet because 8*12=96
Then divide 96 inches by 8 inches. That leaves you with 12 inches.
You would cut a section every 12 inches. That would be 8 cuts.
The answer is 8 sections each being 12 inches.
