1. **State the problem:** We need to find the quotients of the division expressions: - $1248 \div 0.25$ - $1364 \div 44$ - $634.5 \div 4.5$ 2. **Recall the division rule:** Dividing by a decimal can be simplified by multiplying numerator and denominator by a power of 10 to make the divisor a whole number. 3. **Calculate each quotient:** - For $1248 \div 0.25$, multiply numerator and denominator by 100: $$1248 \div 0.25 = \frac{1248 \times 100}{0.25 \times 100} = \frac{124800}{25}$$ Now divide: $$124800 \div 25 = 4992$$ - For $1364 \div 44$, divide directly: $$1364 \div 44 = 31$$ - For $634.5 \div 4.5$, multiply numerator and denominator by 10: $$634.5 \div 4.5 = \frac{6345}{45}$$ Now divide: $$6345 \div 45 = 141$$ 4. **Final answers:** - $1248 \div 0.25 = 4992$ - $1364 \div 44 = 31$ - $634.5 \div 4.5 = 141$
