$$320$$ g

Explanation: To convert kilograms to grams, multiply by 1,000. $$3.2 \times 1,000 = 3,200$$

$$3,200$$ g

Explanation: To convert kilograms to grams, multiply by 1,000. $$3.2 \times 1,000 = 3,200$$

$$32,000$$ g

Explanation: This would be the result if you multiplied by 10,000 instead of 1,000. The correct conversion is $$3.2 \times 1,000 = 3,200$$

$$320,000$$ g

Explanation: This would be the result if you multiplied by 100,000 instead of 1,000. The correct conversion is $$3.2 \times 1,000 = 3,200$$

Explanation: The area of a triangle is given by the formula:
Area = (1/2) × base × height = (1/2) × 10 × 6 = 30 m $$^2$$ .

$$60$$ m $$^2$$
Explanation: This is the result of multiplying the base and height directly (10 × 6), but the correct formula for the area of a triangle is (1/2) × base × height.

$$2.5$$ mg

Explanation: 1 gram = 1000 milligrams, so 0.25 grams = 0.25 × 1000 = 250 milligrams. 2.5 mg is much less than 0.25 grams.

$$25$$ mg

Explanation: 0.25 grams = 250 milligrams, not 25 milligrams. This answer is off by a factor of 10.

$$250$$ mg

Explanation: 1 gram = 1000 milligrams. So, 0.25 grams × 1000 = 250 milligrams. This is the correct answer.

$$2,500$$ mg

Explanation: 0.25 grams = 250 milligrams, not 2,500 milligrams. This answer is off by a factor of 10.

$$11:45$$

Explanation: This is 11:45 in the morning, not in the evening. In 24-hour time, 11:45 am is written as 11:45, but 11:45 pm is different.

$$23:45$$

Explanation: Correct! In 24-hour time, you add 12 to the hour for any time after 12:00 pm (noon). So, 11:45 pm becomes 23:45.

$$21:45$$

Explanation: 21:45 in 24-hour time is 9:45 pm, not 11:45 pm.

$$00:45$$

Explanation: 00:45 in 24-hour time is 12:45 am, which is just after midnight, not 11:45 pm.

$$0.25$$ L

Explanation: To convert millilitres (mL) to litres (L), divide by 1,000.
2,500 mL ÷ 1,000 = 2.5 L. So, 0.25 L is incorrect.

$$2.5$$ L

Explanation: To convert millilitres (mL) to litres (L), divide by 1,000.
2,500 mL ÷ 1,000 = 2.5 L. So, 2.5 L is the correct answer.

$$25$$ L

Explanation: 2,500 mL is much less than 25 L.
2,500 mL ÷ 1,000 = 2.5 L. So, 25 L is incorrect.

$$250$$ L

Explanation: 2,500 mL is much less than 250 L.
2,500 mL ÷ 1,000 = 2.5 L. So, 250 L is incorrect.

$$07:30$$
Explanation: In 24-hour time, times from 12:00 am to 12:59 pm are written the same as in 12-hour time, just with two digits for the hour. So, 7:30 am is 07:30 in 24-hour format.

$$17:30$$
Explanation: 17:30 in 24-hour time is 5:30 pm, not 7:30 am.

$$19:30$$
Explanation: 19:30 in 24-hour time is 7:30 pm, not 7:30 am.

$$23:30$$
Explanation: 23:30 in 24-hour time is 11:30 pm, not 7:30 am.

$$0.6$$ hours
Explanation: 3,600 seconds divided by 3,600 seconds per hour equals 1 hour, not 0.6 hours.

$$1$$ hour
Explanation: There are 3,600 seconds in 1 hour. So, 3,600 seconds ÷ 3,600 seconds/hour = 1 hour.

$$2$$ hours
Explanation: 3,600 seconds is equal to 1 hour, not 2 hours. 2 hours would be 7,200 seconds.

$$3.6$$ hours
Explanation: 3,600 seconds is 1 hour, not 3.6 hours. 3.6 hours would be 12,960 seconds.

$$8$$ m

Explanation: The area of a rectangle is given by Area = length × width. Here, Area = 72 m² and width = 9 m. So, length = Area / width = 72 / 9 = 8 m.
