Question
The length of a pencil is measure with 2 rulers.
Report the length of the pencil from each ruler with the proper number of digits.
Ruler A: ___ dm
Ruler B: ___ dm
ruler a shows the pencil at little over 1 (the halfway line) from 0 to 2
ruler b shows the pencil at 1 1/3 with smaller slash marks in between the 1 and 2 (the rulers are from 0 to 2)

To report the measurements accurately with the proper number of significant figures based on how the rulers are marked:
**Ruler A:** Since ruler A shows the pencil at a little over 1 dm, the measurement can be reported as **1.1 dm**. This indicates the measurement is between 1.0 and 1.2, assuming the precision is to the nearest tenth of a decimeter.
**Ruler B:** Ruler B shows the pencil at 1 1/3 dm, which is equivalent to 1.333... dm. However, for practical measurements, it's more appropriate to round this to two decimal places, which makes it **1.33 dm**.
So, the final reported lengths are:
- Ruler A: **1.1 dm**
- Ruler B: **1.33 dm**
**Ruler A:** Since ruler A shows the pencil at a little over 1 dm, the measurement can be reported as **1.1 dm**. This indicates the measurement is between 1.0 and 1.2, assuming the precision is to the nearest tenth of a decimeter.
