1. Convert 5 kilograms to grams.

• A. 50 grams
• B. 500 grams
• C. 5,000 grams
• D. 50,000 grams

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 5 kilograms is equal to 5,000 grams. Choices A, B, and D are incorrect because they do not correctly convert the given amount of kilograms to grams.

2. What is 0.875 converted to a fraction?

• A. 7/8
• B. 8/7
• C. 3/4
• D. 9/10

Correct answer: A

Rationale: To convert 0.875 to a fraction, we write it as 875/1000. Simplifying by dividing both the numerator and denominator by 125, we get 7/8. Therefore, the correct answer is A. Choice B (8/7) is incorrect as it represents a fraction greater than 1. Choice C (3/4) and Choice D (9/10) do not match the correct conversion of 0.875.

3. What unit is used to measure density in the metric system?

• A. grams per cubic meter (g/m³)
• B. grams per liter (g/L)
• C. grams per cubic centimeter (g/cm³)
• D. grams per square meter (g/m²)

Correct answer: A

Rationale: Density is measured in grams per cubic meter (g/m³) in the metric system. This unit represents the amount of mass (in grams) per unit volume (cubic meter). Choice B, grams per liter (g/L), is incorrect as density is not typically measured in liters. Choice C, grams per cubic centimeter (g/cm³), is a common unit for density but not the standard SI unit. Choice D, grams per square meter (g/m²), is a unit for surface density, not volumetric density. Therefore, the correct unit for measuring density in the metric system is grams per cubic meter (g/m³).

4. Which basic SI conversion is incorrect?

• A. 1 cm = 10 mm
• B. 1 m = 100 cm
• C. 1 km = 1000 m
• D. 1 g = 100 mg

Correct answer: D

Rationale: The correct SI conversion for grams (g) to milligrams (mg) is 1 g = 1000 mg, not 100 mg. Therefore, option D is incorrect. Option A is correct as 1 cm is equal to 10 mm, option B is correct as 1 m equals 100 cm, and option C is correct as 1 km is equivalent to 1000 m. Understanding these basic SI conversions is essential for accurate measurements and calculations in various scientific fields.

5. What is 0.1 kg in grams?

• A. 100 g
• B. 10 g
• C. 1 g
• D. 0.1 g

Correct answer: A

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 0.1 kg equals 100 grams. Choice B (10 g) is incorrect because it represents converting 0.01 kg to grams. Choice C (1 g) is incorrect as it reflects the conversion of 0.001 kg to grams. Choice D (0.1 g) is the value in grams equivalent to 0.01 kg, not 0.1 kg.
