'...using no more than one octal digit to the right of the radix point.'

43.3 base 7 is equal to 31.42857 decimal, not octal. Check your conversion of 0.3 base 7 to octal.

The part to the right of the decimal is still decimal, not yet converted to octal (and the 37 is correct)

???
You must have meant 7-1 x 3
The answer is 37.3........
Is it that?
.4285710 = 4 * 10-1 + 2 * 10-2 + 8 * 10-3 + 5 * 10-4 + 7 * 10-5

Now you need to convert this into a sum of negative powers of 8.
