Here are the solutions to the metric unit conversion problems.

Key Rule:
* 1 metric ton (t) = 1,000 kilograms (kg)
* To go from kg to t, divide by 1,000.
* To go from t to kg, multiply by 1,000.

A) Convert between metric tons (t) and kilograms (kg).

1) $10,000 \text{ kg} = \_\_\_\_\_ \text{ t}$
* Calculation: $10,000 \div 1,000 = 10$
* Answer: 10 t

2) $16 \text{ t} = \_\_\_\_\_ \text{ kg}$
* Calculation: $16 \times 1,000 = 16,000$
* Answer: 16,000 kg

3) $61 \text{ t} = \_\_\_\_\_ \text{ kg}$
* Calculation: $61 \times 1,000 = 61,000$
* Answer: 61,000 kg

4) $24,000 \text{ kg} = \_\_\_\_\_ \text{ t}$
* Calculation: $24,000 \div 1,000 = 24$
* Answer: 24 t

5) $95,000 \text{ kg} = \_\_\_\_\_ \text{ t}$
* Calculation: $95,000 \div 1,000 = 95$
* Answer: 95 t

6) $5 \text{ t} = \_\_\_\_\_ \text{ kg}$
* Calculation: $5 \times 1,000 = 5,000$
* Answer: 5,000 kg

B) Complete the unit conversion table.

* Column 1: Given 6,000 kg.
* $6,000 \div 1,000 = 6$ metric tons.
* Column 2: Given 11 metric tons.
* $11 \times 1,000 = 11,000$ kg.
* Column 3: Given 27,000 kg.
* $27,000 \div 1,000 = 27$ metric tons.
* Column 4: Given 30 metric tons.
* $30 \times 1,000 = 30,000$ kg.
* Column 5: Given 41,000 kg.
* $41,000 \div 1,000 = 41$ metric tons.
* Column 6: Given 45 metric tons.
* $45 \times 1,000 = 45,000$ kg.

Filled Table Values:
* Row "metric tons": 6, 11, 27, 30, 41, 45
* Row "kilograms": 6,000, 11,000, 27,000, 30,000, 41,000, 45,000

C) Compare using <, >, or =.

1) $57 \text{ t} \quad \square \quad 56,805 \text{ kg}$
* Convert 57 t to kg: $57,000 \text{ kg}$.
* $57,000 > 56,805$
* Answer: >

2) $46,090 \text{ kg} \quad \square \quad 46 \text{ t}$
* Convert 46 t to kg: $46,000 \text{ kg}$.
* $46,090 > 46,000$
* Answer: >

3) $62,920 \text{ kg} \quad \square \quad 63 \text{ t}$
* Convert 63 t to kg: $63,000 \text{ kg}$.
* $62,920 < 63,000$
* Answer: <

4) $73 \text{ t} \quad \square \quad 73,250 \text{ kg}$
* Convert 73 t to kg: $73,000 \text{ kg}$.
* $73,000 < 73,250$
* Answer: <

5) $21 \text{ t} \quad \square \quad 21,000 \text{ kg}$
* Convert 21 t to kg: $21,000 \text{ kg}$.
* They are equal.
* Answer: =

6) $58,000 \text{ kg} \quad \square \quad 58 \text{ t}$
* Convert 58 t to kg: $58,000 \text{ kg}$.
* They are equal.
* Answer: =

7) $38,000 \text{ kg} \quad \square \quad 38 \text{ t}$
* Convert 38 t to kg: $38,000 \text{ kg}$.
* They are equal.
* Answer: =

8) $90 \text{ t} \quad \square \quad 89,926 \text{ kg}$
* Convert 90 t to kg: $90,000 \text{ kg}$.
* $90,000 > 89,926$
* Answer: >
