1. **State the problem:** We need to calculate the division $6.48 \div 1.6$. 2. **Recall the division rule:** Dividing decimals can be simplified by multiplying both the dividend and divisor by the same power of 10 to make the divisor a whole number. 3. **Multiply numerator and denominator by 10:** $$\frac{6.48}{1.6} = \frac{6.48 \times 10}{1.6 \times 10} = \frac{64.8}{16}$$ 4. **Perform the division:** $$64.8 \div 16 = 4.05$$ 5. **Conclusion:** The result of $6.48 \div 1.6$ is $4.05$.
