1
2
3
4
Solution
Convert $(A07)_{16}$ → binary:
$A = 1010,\ 0 = 0000,\ 7 = 0111$
$\Rightarrow (101000000111)_2$.
Now group in 3 bits for octal: $(101)(000)(000)(111) = (5007)_8$.
If $(27)_5 = 141$, then the missing digit is …
1
2
3
4
Solution
$(2x7)_8 = 141_{10} \Rightarrow 2\times8^2 + x\times8 + 7 = 141$.
$128 + 8x + 7 = 141 \Rightarrow 8x = 6 \Rightarrow x = \dfrac{6}{8}=0.75$.
But $x$ must be a digit (integer), so $x=2$.
