Question 1

The location of the arrow is 3(5/16) inches.

The position marked by the arrow on the ruler corresponds precisely to 3(5/16) inches, indicating the correct measurement as represented in the options.

A) 3(1/4) inches

This option represents a measurement equivalent to 3.25 inches. The position of the arrow does not align with this value, as it is positioned slightly beyond 3.25 inches on the ruler.

B) 3(3/8) inches

This choice corresponds to 3.375 inches. Again, the arrow is not located at this position; it is further along the scale, making this option incorrect.

C) 3(5/16) inches

This option is correct since 3(5/16) inches equals 3.3125 inches, which accurately reflects the position of the arrow on the ruler. The measurement is correctly identified as being between 3(1/4) and 3(3/8) inches.

D) 3(1/3) inches

This option translates to approximately 3.333 inches, which is also incorrect. The arrow does not indicate this measurement, as it is positioned closer to 3(5/16) inches.

Conclusion

The correct answer, 3(5/16) inches, is definitively supported by the ruler's markings. All other options fail to accurately represent the arrow's position, being either too low or too high on the scale. This illustrates the importance of precise measurement in reading a ruler accurately.
