Which is more precise measurement? A:18 inches B:18.55 C:17.5 D: 17.775

17.775 is the most precise since it has the most decimals. However, it may not be correct.

option D

Step-by-step explanation:

the correct answer is option D

A precise measurement is one in which we can measure the smallest of the value.

In 17.775 we can measure the smallest value of 0.001

In 18.55 we can measure smallest value up to 0.01

In 17.5 we can measure smallest value up to 0.1

In 18 we can measure smallest value of 1.

hence, the correct answer will be option D which will be 17.775 in which we can measure 0.001 value.
