'...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)

7¹x3 =0.42857...
The answer is 37.3...
Is it that?

7¹x3 =0.42857...

?
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.
