As I know by 0.21 x8 and -4 for the answer to convert to base 8.

However, I could not calculate and keep on expanding the value to millions.

  • $\begingroup$ have you seen and followed m.wikihow.com/Convert-from-Decimal-to-Octal. Can you convert .1 or 1/10 to base 8. What step are you having trouble with? $\endgroup$ – shai horowitz May 17 '16 at 19:55
  • $\begingroup$ Thanks for your time, I'm currently having problem to multiple 0.21 with 8 and -4 when the answer is 4 $\endgroup$ – twintwinkle May 17 '16 at 19:59

$\frac18<0.21 <\frac28\\ 0.21-\frac18 = 0.085\\ 0.085*64 = 5.4\\ 0.085 - \frac5{64} = 0.006875\\ 0.006875 * 8^3 = 3.5\\ 0.006875 - \frac 3{8^3} = 0.00101625\\ $

etc.

$0.153$
