# Measuring Precision of Metal Bar with Rulers A and B

## Measuring Precision with Rulers A and B

**Ruler A:** Ruler A can measure the length of the metal bar to the nearest tenth of a centimeter. This means that it can provide measurements with one decimal digit after the decimal point, such as 2.3 cm.

**Ruler B:** On the other hand, Ruler B is capable of measuring the length to the nearest hundredth of a centimeter. It can provide measurements with two decimal digits after the decimal point, for example, 2.36 cm.

Therefore, when using Ruler A and Ruler B to measure the metal bar, Ruler A provides a slightly higher degree of precision with measurements to the nearest hundredth, while Ruler B offers measurements to the nearest tenth.
