🔍 Key Concepts

• How micrometer ranges work (a 1–2 inch micrometer already includes 1 inch in its frame) • How to interpret a decimal reading like 0.250 in micrometer terms • Converting thousandths of an inch (0.250) into a simple fraction

💭 Think About

• Ask yourself: On a 1–2 inch micrometer, does the reading shown represent the total size, or the amount ADDED to the base 1 inch? • Think about what 0.250 means in inches—how does 0.250 compare to common fractions like 1/4, 1/2, and 3/4? • After you know the decimal value as a fraction, decide whether you must add it to 1 inch or 2 inches based on the range.

✅ Before You Answer

• Confirm that 0.250 inch equals a common fraction you recognize • Confirm whether the micrometer’s lower range value (1 inch) must be added to the reading • Eliminate any choices that would give a measurement outside the 1–2 inch range of the micrometer
