base 3 means you have a value range of 0 1 2 as each digit
start from the right..
in base 3 you have weighting for each digit of 1,3,9,27,81,243 onwards as you go up the number
so now you need to apply weighting to your numbers
1 * 1 = 1
0 * 3 = 0
2 * 9 = 18
2 * 27 = 54
1 * 81 = 81
2 * 243 = 486
add up the right column 1+0+18+54+81+486 = 640
answer is 640
it is like binary conversion in that binary doubles 1,2,4,8,16 etc.. to convert to base 10, in base 3 it triples.. so base2 - double, base3 - triple , a worthwhile way to remember it.

ok so 1/3 is 0.3333333....
and 2/3 is 0.6666666....
that's just what it is, if you're dong a maths problem just put it into your calculator as 1/3 etc.
