@ LordeCalifornia (and to others that may get confused by my sloppy explanation) I am sorry. I should have been more explicit

0.75
* 6
-----
4 5
* 6
----
3 0
The best strategy is to convert the fraction to decimal. So we all know how I arrived at 0.75. The zero (0) is really part of the answer, so we are done with that. So we will mentally put it aside (it is part of the final answer). We will only multiply the figures to the right of radix (.) You may decide to ignore the radix (.), mentally that is. The trick is ALWAYS IGNORE the leftmost figure, so now multiply .75 * 6. This gives (4) 5
What do we do next? Mentally keep away the 4 (it is part of the answer). We are left with (.)5
What next? Multiply the 5 with 6. That gives us (3) 0. Now we know we are in the terminal point because even if we multiply 0 by 6 it will still give 0, so we know we are done.

Please go through the steps with the new explanation and you will understand.

I sincerely hope I am more explicit, and sorry for not making myself clear.

Cheers and God bless

thanks a million! smiley

Welcome back. And how was the new year holiday? We are now back and let's get going. Remember what I wrote the other day when I said: 4 = 1002. It simply means 4 in base 10 is equal to 1002 in base 2. We have been 'wired' to think in base 10. Other bases exist naturally. We have 7-day week which is in base 7.

I suggest you write the workings on paper and upload, typing is kind of confusing. thanks in advance.

This is criminally easy

3/4 = X6
By way of explanation, first let's consider a random number 6842(say). To convert to base x, we simply do this:
6 * x4 + 8 * x3 + 4 * x2 + 2 * x1.

Similarly, to convert 0.6842 to base x, we multiply repeatedly by the base until it equals to 0
The first thing we should do is to convert the fraction to its decimal equivalent. Thus, 3/4 = 0.75. As I indicated above, continue multiplying the fractions to the right of decimal point until multiplication is no more possible.

0.75
* 6
-----
4 5
* 6
----
3 0

Iterating from top to buttom (the bolded), we have 0.43
You can see it is dead easy
