 So we already saw that these numbers are equal. We were able to convert them from decimal to binary. And we could then convert these binary numbers into octal, say by finding groups of three bets or hexadecimal by looking for groups of four bets. We can also convert directly from decimal to octal or decimal to hexadecimal. And we're going to use the same procedure that we did before. We're just going to be working with a different base. So if I start with my 13.625, and I'm going to break my number into two parts. And I'm going to work with the whole number part. So 13 and octal is 8 plus 5. So that will be 15. Now I'll deal with my fractions separately. So I'm going to use the multiplication method. I'm just going to take my fraction and I'm going to continue multiplying by my base, which will be 8. So 0.625 times 8, 16 plus 4 gives me 20, 48 plus 2 gives me 50. So 0.625 times 8 is 5. So I would write down the 5 here. Since I have nothing else here to multiply by 8, I'm done. I can stop here and if I look, that's exactly what we expected from just converting the binary number directly. I can do the same thing with 6.5625 and I can convert that to hexadecimal. 6 and decimal will turn into a 6 in hexadecimal as well. So I'm just going to keep that. Now I have the 0.5625 and I'm going to multiply this by 16, because that's my destination base. 6 times 5 is 30, 6 times 2 is 12, plus 3 is 15. 6 times 6 is 36, plus 1 is 37. 6 times 5 is 30, plus 3 is 33. And then one times 56.25 is 56.25. So 0.5625 times 16 is 9. So I'll write down my 9. I have nothing left here to multiply by 16, so I'm done. My result is negative 6.9. Almost matches what I've got over here, except that my whole numbers are mismatched on this side. If I change all of these two fives, then that's all consistent and it makes sense.
