Explanation:

Question 1: Convert 12.7 feet to inches

Step1: Recall the conversion factor (1 foot = 12 inches)

To convert feet to inches, we use the conversion factor \( 1\ \text{ft} = 12\ \text{in} \). So we multiply the number of feet by 12.

Step2: Perform the calculation

\( 12.7\ \text{ft} \times 12\ \text{in/ft} = 152.4\ \text{in} \)

Step1: Recall the conversion factors (1 m = 100 cm, 1 km = 1000 m)

First, convert centimeters to meters by dividing by 100 (since \( 1\ \text{m} = 100\ \text{cm} \)), then convert meters to kilometers by dividing by 1000 (since \( 1\ \text{km} = 1000\ \text{m} \)).

Step2: Convert centimeters to meters

\( 420000\ \text{cm} \div 100\ \text{cm/m} = 4200\ \text{m} \)

Step3: Convert meters to kilometers

\( 4200\ \text{m} \div 1000\ \text{m/km} = 4.2\ \text{km} \)

Step1: Recall the conversion factors (1 km = 1000 m, 1 m = 100 cm)

First, convert kilometers to meters by multiplying by 1000, then convert meters to centimeters by multiplying by 100.

Step2: Convert kilometers to meters

\( 5.2\ \text{km} \times 1000\ \text{m/km} = 5200\ \text{m} \)

Step3: Convert meters to centimeters

\( 5200\ \text{m} \times 100\ \text{cm/m} = 520000\ \text{cm} \)

Answer:

152.4
