Question

A scale measures to 1/10, or 0.1, of a pound. What is the most appropriate way to report a measurement using this scale?

130 pounds
Between 100 and 200 pounds
132.3 pounds
132 pounds

Answer 1

The most appropriate way to report a measurement using a scale that measures to 1/10 (or 0.1) of a pound is to include one decimal place. This means you would want a precision level that reflects the scale's capability.

Considering the options:

- **130 pounds** (no decimal, not precise)
- **Between 100 and 200 pounds** (too vague)
- **132.3 pounds** (includes decimal, precise)
- **132 pounds** (no decimal, not precise)

Therefore, the best answer is **132.3 pounds**, as it accurately reflects the scale's precision of 0.1 pounds.
