Question

Using the chart, which state would have had the best representation according to the Three Fifths Compromise. slave

Answer 1

I can't see the chart you mention. However, the Three‑Fifths Compromise gave each state representation = free (and white) population + 3/5 of the enslaved population. So whichever state had the largest enslaved population would gain the most extra representation — historically that was Virginia (and other large slave states like South Carolina and North Carolina also benefited).

If you want a precise answer from your chart, either paste the numbers here or upload the chart/image. I can then compute for each state using this formula:
Representation count for apportionment = free population + 0.6 × enslaved population

Example: if a state had 100,000 free people and 80,000 enslaved people, its apportionment population would be
100,000 + 0.6×80,000 = 148,000.
