Use the painted rulers below to measure the length of each line segment.

1. 

   Hint (a):

   Try to remember how you found the length of the rulers Ms. Mikles took in problem 2-2 in class.

   Answer (a):

   One way is to count the whole parts and then the leftover parts. For this problem, count two whole inches (one from $2$ to $3$ and the other from the $3$ to $4$). Then, count the half inch (from $1.5$ to $2$).

   

2. 

   Hint (b):

   This one is just like the one above. Remember to count the whole centimeters and then the partial centimeters.

3. 

   Hint (c):

   Try to count the number of whole inches and then the number of quarter inches and half inches.
