Question

A manufacturing company uses three measuring tools to

measure lengths. The tools are tested using a standard
unit exactly 7 cm long. The results are as follows.
a. Which tool gives the most precise measurement?
​

Answer 1

Precision is how detailed a measurement is.

7.033 has 3 digits after the decimal point

6.91 has 2 digits after the decimal point

7.1 has a single digit after the decimal point.

Since 7.033 has the most digits after the decimal point, it is more precise than the others.
