e. 27 m = ______ cm
f. 0.65 cm = ______ mm
g. 36 mm = ______ cm
h. 2 730 m = ______ km
i. 1.35 m = ______ cm
j. 89 cm = ______ m
k. 3 687 m = ______ km
l. 56 cm = ______ mm

Explanation:

Part a

Step1: Recall the conversion factor (1 km = 1000 m)

To convert kilometers to meters, we multiply the number of kilometers by 1000. So for \(12\) km, we use the formula \( \text{meters} = \text{kilometers} \times 1000 \).

Step2: Perform the calculation

\(12\times1000 = 12000\)

Step1: Recall the conversion factor (1 m = 100 cm)

To convert centimeters to meters, we divide the number of centimeters by 100. So for \(2730\) cm, we use the formula \( \text{meters} = \frac{\text{centimeters}}{100} \).

Step2: Perform the calculation

\(\frac{2730}{100}=27.3\)

Step1: Recall the conversion factor (1 km = 1000 m)

To convert kilometers to meters, we multiply the number of kilometers by 1000. So for \(0.15\) km, we use the formula \( \text{meters} = \text{kilometers} \times 1000 \).

Step2: Perform the calculation

\(0.15\times1000 = 150\)

Answer:

\(12000\)
