Convert from base 5 to base 10
432five = (4 x 52) + (3 x 51) + (2 x 50)
= (4 x 25) + (3 x 5) + (2 x 1)
= 100 + 15 + 2
= 117ten
Then convert from base 10 to base 3
| 3 | 117 |
| 3 | 39 r 0 |
| 3 | 13 r 0 |
| 3 | 4 r 1 |
| 3 | 1 r 1 |
| 0 r 1 |
Selecting the remainders from bottom to top:
117ten = 11100three
Hence; 432five = 11100three
