20000 = $$2(3/2)^4$$ = 162/16. This rounds to 10, which in base 3/2 is 2101.
100000 = $$(3/2)^5$$ = 243/32. This rounds to 8, which in base 3/2 is 212.
200000 = $$2(3/2)^5$$ = 486/32. This rounds to 15, which in base 3/2 is 21010.
1000000 = $$(3/2)^6$$ = 729/64. This rounds to 11, which in base 3/2 is 2102.
