Reading a Ruler is very easy. This is only if you are using whole numbers for inches and centimeters. here are a few easy steps on how we can read the ruler.
1. There are 2 different measurement systems in rulers. English and Metric. If you don't find the sides to be labelled, its easy to make out which side is inches and which side is centimeters just by looking between the lines.
2. Now if you watch it, you will find 9 lines between each centimeter that make up one millimeter. So naturally 10 millimeters would make up a centimeter. This is useful in terms of metric calculation.
3. If its inches, the number of lines would be seven instead of 9. So depending on what system you want to use is makes up your reading of the ruler. If you are using Metrics, use centimeters or if you use English, use inches.
4. When starting to measure, see that your start and end points are perfectly placed. Also take note of the points. The later point is what makes up the measurement.
5. Suppose you end up on not a whole number, say you are using centimeters as preferred choice of measurement i.e metric system. You start to measure and you end up at a non whole number such as 5 lines after 3 number, then your measurement would be 3.5 centimeters i.e 3 centimeters and 5 millimeters.

you read a ruler by conting the little lines first
Yes!
A ruler or scale should not be read to less than the smallest graduation. In practice, in-between measurements can be estimated but they are not significant.
You look at the markings on its edge.
You could align the edge of the object with the zero on the ruler and then read off the marking on the ruler which aligned with the other end of the object.

To record measurements using a ruler, place the ruler next to the object to be measured. Ensure that the zero mark on the ruler aligns with one end of the object. Read the measurement where the other end of the object falls on the ruler and record it in the appropriate units.

You have to give the choices. I am not a wizard, so I can't read your mind.

To use a ruler, place the 0 mark at one end of the object you want to measure. Then, read the measurement at the opposite end where it aligns with the ruler markings. Make sure to use the correct units (inches, centimeters, etc.) as indicated on the ruler.
