1. Convert 16 yards to feet. We know the conversion rate: 1 yard = 3 feet. So, multiply 16 yards by 3 feet per yard: $$16 \times 3 = 48$$ Therefore, 16 yards equals 48 feet. 2. Convert 10 pints to quarts. Given: 1 quart = 2 pints. To find quarts, divide pints by 2: $$10 \div 2 = 5$$ So, 10 pints equals 5 quarts. 3. Convert 12 ounces to pounds. Given: 16 ounces = 1 pound. To convert ounces to pounds, divide ounces by 16: $$12 \div 16 = \frac{12}{16}$$ Simplify the fraction by dividing numerator and denominator by 4: $$\frac{\cancel{12}^3}{\cancel{16}^4} = \frac{3}{4}$$ Therefore, 12 ounces equals $\frac{3}{4}$ pounds. 4. Express 4,224 feet in a different unit or context is not specified, so it remains 4,224 feet.
