Solve the following subtraction problems involving meters and centimeters: 1. 37 m 39 cm - 9 m 17 cm 2. 8 m 47 cm - 3 m 30 cm 3. 8 m 29 cm - 2 m 13 cm

$$37 \text{ m} - 9 \text{ m} = 28 \text{ m}$$

The result is $28 \text{ m } 22 \text{ cm}$.
The correct option is (c).

$$\boxed{\text{(c) } 28 \text{ m } 22 \text{ cm}}$$

9. $8 \text{ m } 47 \text{ cm} - 3 \text{ m } 30 \text{ cm}$

$$8 \text{ m} - 3 \text{ m} = 5 \text{ m}$$

The result is $5 \text{ m } 17 \text{ cm}$.
The correct option is (d).

$$\boxed{\text{(d) } 5 \text{ m } 17 \text{ cm}}$$

10. $8 \text{ m } 29 \text{ cm} - 2 \text{ m } 13 \text{ cm}$

$$8 \text{ m} - 2 \text{ m} = 6 \text{ m}$$

The result is $6 \text{ m } 16 \text{ cm}$.
The correct option is (a).

$$\boxed{\text{(a) } 6 \text{ m } 16 \text{ cm}}$$
