Answer 1

a) 645₈

_{=> (6 * 8^2) + (6 * 8^1) + (5 * 8^0)= 421}

_b) 5BF₁₆

=> (5 * 16 ^2) + ( B * 16^1) + (F* 16^0)=1471

c)   101011₂

_{101011= (1 * 2^5) + (0 * 2^4) + (1 * 2^3) + (0 * 2^2) + (1 *2^1) +(1 * 2^0)=43}

_d) 195₁₀

195 ÷ 2 = 97 + 1;

97 ÷ 2 = 48 + 1;

48 ÷ 2 = 24 + 0;

24 ÷ 2 = 12 + 0;

12 ÷ 2 = 6 + 0;

6 ÷ 2 = 3 + 0;

3 ÷ 2 = 1 + 1;

1 ÷ 2 = 0 + 1;

195= 1100 0011

part 2

a) 0.1001₂

_{.1001 = (1 × 2^-1) + (0 × 2^-2) + (0 × 2^-3) + (1 × 2^-4) = 0.5625}

_b) 1011101₂ + 1110₂₌

1110 + 1011101
= 01101011
