Fill in the correct circle that corresponds to the best answer. 7. Which of the following is not a common unit of measurem for the customary system? \( \begin{array}{ll}\text { (A) feet } & \text { (C) meter } \\ \text { (B) inches } & \text { (D) miles }\end{array} \)

The meter is actually a unit of measurement from the metric system, while feet, inches, and miles are all commonly used in the customary system. This makes meter the odd one out! It’s a fun little quirk of measurement systems, showing how different regions prefer different units to measure distance. For a little context, the customary system is mainly used in the United States, while most other countries use the metric system, which makes for some interesting international conversion challenges. Just think of all those times you're measuring distance and need to convert from miles to kilometers – talk about a math moment!
