Nan wants to measure the length of board. Which of the following units would be the most precise?

A. inch
B. foot
C. 1/16 inch
D. 1/8 inch

We could use inches or fractions of an inch to measure the length or width of our finger nail.

Which do you think would be a better measurement of a board?

To determine which unit would be the most precise for measuring the length of the board, we need to compare the options provided.

A. Inches: The inch is a commonly used unit of length. It provides a moderate level of precision.

B. Foot: The foot is a larger unit compared to the inch. It is less precise than the inch because it represents a larger measurement.

C. 1/16 inch: This option provides an increased level of precision compared to just inches. It is more accurate since it represents a smaller fraction of an inch.

D. 1/8 inch: Similarly to option C, this option provides an even higher level of precision compared to the inch. It represents an even smaller fraction of an inch.

Based on this analysis, the most precise option for measuring the length of the board would be option D, 1/8 inch.
