Question

note: 1 kilometer (km) = 1,000 meter (m)
1 m = 100 centimeters (cm) = 1,000 millimeters (mm)
convert to the units shown:

1. 73 m = × 1,000 = 73,000 mm
2. 45 m = ______ mm
3. 20 m = ______ cm
4. 49 m = ______ cm
5. 67 m = ______ cm
6. 89 m = ______ cm
7. 13 m = ______ mm
8. 17 cm = ______ mm
9. 22 m = ______ cm
10. 31 m = ______ cm

convert to the units shown:

Explanation:

Step1: Use m to mm conversion

Since $1\ \text{m}=1000\ \text{mm}$, multiply meters by 1000.

1. $73\ \text{m} = 73 \times 1000 = 73000\ \text{mm}$
2. $45\ \text{m} = 45 \times 1000 = 45000\ \text{mm}$
3. $13\ \text{m} = 13 \times 1000 = 13000\ \text{mm}$

Step2: Use m to cm conversion

Since $1\ \text{m}=100\ \text{cm}$, multiply meters by 100.

1. $20\ \text{m} = 20 \times 100 = 2000\ \text{cm}$
2. $49\ \text{m} = 49 \times 100 = 4900\ \text{cm}$
3. $67\ \text{m} = 67 \times 100 = 6700\ \text{cm}$
4. $89\ \text{m} = 89 \times 100 = 8900\ \text{cm}$
5. $22\ \text{m} = 22 \times 100 = 2200\ \text{cm}$
6. $31\ \text{m} = 31 \times 100 = 3100\ \text{cm}$

Step3: Use cm to mm conversion

Since $1\ \text{cm}=10\ \text{mm}$, multiply cm by 10.

1. $17\ \text{cm} = 17 \times 10 = 170\ \text{mm}$

Answer:

1. $73000$ mm
2. $45000$ mm
3. $2000$ cm
4. $4900$ cm
5. $6700$ cm
6. $8900$ cm
7. $13000$ mm
8. $170$ mm
9. $2200$ cm
10. $3100$ cm
