Question

which measurement is more precise?
0.25 grams
1.25 grams
0.005 grams
0.10 grams

Explanation:

Precision in measurements is determined by the smallest unit the measurement can detect, which corresponds to the number of decimal places. A measurement with more decimal places can distinguish smaller differences, making it more precise. Comparing the options:

• 0.25 grams (2 decimal places, smallest unit 0.01 g)
• 1.25 grams (2 decimal places, smallest unit 0.01 g)
• 0.005 grams (3 decimal places, smallest unit 0.001 g)
• 0.10 grams (2 decimal places, smallest unit 0.01 g)

0.005 grams has the most decimal places, meaning it measures to the smallest unit, so it is the most precise.

Answer:

0.005 grams
