Solution - Base conversion

2, 225

2,225

Step-by-step explanation

${(8 B 1)}_{16} = b a s e 10$

Identify the source number, source base, and target base before converting through base 10.

${(8 B 1)}_{16} = 8 \cdot 16^{2} + 11 \cdot 16^{1} + 1 \cdot 16^{0}$

$8 \cdot 16^{2} + 11 \cdot 16^{1} + 1 \cdot 16^{0} = 2225$

Expand each digit by place value: $8 \cdot 16^{2}$
+ $11 \cdot 16^{1}$
+ $1 \cdot 16^{0}$ . This gives $2, 225$ in base 10.

$\frac{2225}{10} = 222 r e m a \in d e r 5$

$\frac{222}{10} = 22 r e m a \in d e r 2$

$\frac{22}{10} = 2 r e m a \in d e r 2$

$\frac{2}{10} = 0 r e m a \in d e r 2$

$5 \to 2 \to 2 \to 2 = 2225$

$2225 (b a s e 10) = {(2225)}_{10}$

Repeatedly divide $2, 225$ by $10$ , collect remainders, and read them in reverse to get $2, 225$ .
