What number is plotted on the number line?
0.3
о
1.3
1.7

answer:

0.7

Step-by-step explanation:

Each of the smaller notches is equal to 1/10, or 0.1. You could count backwards from 1 three notches, subtracting 0.1 each time, to get to 0.7.

1 (start)

0.9 (1 notch)

0.8 (2 notches)

0.7 (3 notches)

Or, you could count up from 0. The notch highlighted is the seventh notch.

0 (start)

0.1 (1 notch)

0.2 (2 notches)

0.3 (3 notches)

0.4 (4 notches)

0.5 (5 notches)

0.6 (6 notches)

0.7 (7 notches)

both equations and proportions are better.
