- 1) Draw a long line on a piece of paper. This will be the base of your number line
2) Make hash marks on your line. This will make it look like a train track
3) On the left, start writing numbers above the hashmarks. Start with zero above the first hashmark on the left
4) Stop numbering at 20.(2 votes)

- [Voiceover] We're on the fractions on the number line
exercise on Khan Academy, and they ask us to move the orange dot to three-fourths on the number line. Change the number of divisions to create tick marks on the number line. Let's see what's going on here. I have the space from zero
to one on the number line. If I want to move it to three-fourths, what I would first want to do is divide the space between
zero and one into fourths, into four equal sections. I would want to have four divisions here. And there you have it, four divisions. I typed in the number four
and have four equal divisions. One, two, three, four. This is going to be a fourth,
that's another fourth, that's another fourth,
and that's another fourth. What we care about is three-fourths. Once again, that's one-fourth, this would be another fourth, getting us to two-fourths, and then this would be another fourth, getting us to three-fourths. So, there you have it. That is three-fourths on the number line.
