Decimal number line worksheet for students to identify and write decimals on a number line.

Looking at the bottom number line from 6 to 8, I can see that there are 10 equal intervals between 6 and 7, and another 10 equal intervals between 7 and 8. This means each small tick mark represents 0.1 (one-tenth), just like the top number line.

I can now determine the decimal value for each lettered point on this number line:
- Point 'm' is at the first tick mark after 6, so it's 6.1
- Point 'n' is at the second tick mark after 6, so it's 6.2
- Point 'o' is at the fourth tick mark after 6, so it's 6.4
- Point 'p' is at the sixth tick mark after 6, so it's 6.6
- Point 'q' is at the seventh tick mark after 6, so it's 6.7
- Point 'r' is at the ninth tick mark after 6, so it's 6.9
- Point 's' is at the tenth tick mark after 6, which is exactly at 7.0
- Point 't' is at the second tick mark after 7, so it's 7.2
- Point 'u' is at the fourth tick mark after 7, so it's 7.4
- Point 'v' is at the seventh tick mark after 7, so it's 7.7
- Point 'w' is at the ninth tick mark after 7, so it's 7.9
- Point 'x' is at the tenth tick mark after 7, which is exactly at 8.0

Now I have all the decimal values for both number lines. Let me compile the complete solution.

The solution to the decimal number line problem is:

Top number line (0 to 2):
a. 0.1
b. 0.2
c. 0.4
d. 0.6
e. 0.7
f. 0.9
g. 1.0
h. 1.2
i. 1.4
j. 1.7
k. 1.9
l. 2.0

Bottom number line (6 to 8):
m. 6.1
n. 6.2
o. 6.4
p. 6.6
q. 6.7
r. 6.9
s. 7.0
t. 7.2
u. 7.4
v. 7.7
w. 7.9
x. 8.0
