Let's solve these conversions step by step:

A) Convert 2.2 miles to yards

We know that:

• 1 mile = 1760 yards

So: $2.2 \, \text{miles} \times 1760 \, \text{yards/mile} = 3872 \, \text{yards}$ Answer: 2.2 miles = 3872 yards

B) Convert 5.8 kilometers to meters

We know that:

• 1 kilometer = 1000 meters

So: $5.8 \, \text{km} \times 1000 \, \text{m/km} = 5800 \, \text{m}$ Answer: 5.8 kilometers = 5800 meters

C) Convert 904 meters to kilometers

We know that:

• 1 kilometer = 1000 meters

So: $904 \, \text{m} \div 1000 = 0.904 \, \text{km}$ Answer: 904 meters = 0.904 kilometers

D) Convert 12 cm to inches

We know that:

• 1 inch = 2.54 cm

So: $12 \, \text{cm} \div 2.54 = 4.7244 \, \text{inches} \, (\text{rounded to four decimal places})$ Answer: 12 cm = 4.7244 inches
