Find the difference of weights given below. 1. 34 kg - 12 kg 2. 249 kg - 136 kg 3. 542 kg - 299 kg 4. 36 kg 27 g - 24 kg 12 g 5. 94 kg 174 g - 39 kg 098 g 6. 298 kg 248 g - 149 kg 248 g

$$34 - 12 = 22$$

The difference is $22 \text{ kg}$.

$$\boxed{\text{22 kg}}$$

2.

$$249 \text{ kg} - 136 \text{ kg}$$

$$249 - 136 = 113$$

The difference is $113 \text{ kg}$.

$$\boxed{\text{113 kg}}$$

3.

$$542 \text{ kg} - 299 \text{ kg}$$

$$542 - 299 = 243$$

The difference is $243 \text{ kg}$.

$$\boxed{\text{243 kg}}$$

4.

$$36 \text{ kg } 27 \text{ g} - 24 \text{ kg } 12 \text{ g}$$

$$36 \text{ kg} - 24 \text{ kg} = 12 \text{ kg}$$

The difference is $12 \text{ kg } 15 \text{ g}$.

$$\boxed{\text{12 kg 15 g}}$$

5.

$$94 \text{ kg } 174 \text{ g} - 39 \text{ kg } 098 \text{ g}$$

We need to borrow from kilograms because $174 < 098$ is incorrect. $174 > 98$, so we can subtract directly.

$$174 \text{ g} - 98 \text{ g} = 76 \text{ g}$$

$$94 \text{ kg} - 39 \text{ kg} = 55 \text{ kg}$$

The difference is $55 \text{ kg } 76 \text{ g}$.

$$\boxed{\text{55 kg 76 g}}$$

6.

$$298 \text{ kg } 248 \text{ g} - 149 \text{ kg } 248 \text{ g}$$

$$298 \text{ kg} - 149 \text{ kg} = 149 \text{ kg}$$

The difference is $149 \text{ kg } 0 \text{ g}$.

$$\boxed{\text{149 kg 0 g}}$$
