You're on a roll — 1. ii) Change 85 base 10 to base 6. Step 1: Divide $85$ by $6$ and note the remainder. $$85 \div 6 = 14 \text{ remainder } 1$$ Step 2: Divide the quotient $14$ by $6$ and note the remainder. $$14 \div 6 = 2 \text{ remainder } 2$$ Step 3: Divide the quotient $2$ by $6$ and note the remainder. $$2 \div 6 = 0 \text{ remainder } 2$$ Step 4: Read the remainders from bottom to top. The remainders are $2, 2, 1$. Therefore, $85_{10}$ in base 6 is: $$\boxed{221_6}$$ Send me the next one 📸
