Which measurement is the most precise; 2 in., 2.5 in., 2.675 in., or 2 3/4 in. ?

Step-by-step explanation:

Precision is obtained according the number of significative digits it has a measure. Significative digits refer to the total number of digits that have some value for a measure.

Among options, the second choice is the one that has more significative digits. 2.675 has four significative digits which means that this measure gives more information that other options, because the first one is equal to 2.75 (3 significative digits), third one 2 has only one significative digit, and last choice has only two.

Therefore, the right answer is 2.675 in.
