I'm suppose to figure out the radix r of these 2 numbers:

(BEE)r = (2699)10; //the 10 means base 10

Of course r has to be 16 because HEX is the only one with A-F

(365)r = (194)10;

Is there an easy way to figure out the radix here or do i just have to convert 194 to each of the bases and see which one works out?

Also if i wnated to convert

310.2 base 4 to octal, would i just divide by 8 as if u were going to convert a decimal to octal or would I first convert it to decimal by this method:

4^2 * 3 + 4^1x1 + 0 + .5 = 52.5 base 10 now divide by 8 and multiply by 1/8 to get the decimal part.
