  • - [Instructor] In this video, we're going to try

  • to figure out what 0.6 or 6/10 divided by two is.

  • And I'll give you a little bit of a hint.

  • We have 6/10 plotted on the number line right over here.

  • And so one way to think about it is,

  • if I wanted to go from zero to 6/10 in two jumps,

  • how big would each of those jumps have to be?

  • Pause this video and try to figure that out on your own

  • before we work through it together.

  • All right, so as I mentioned,

  • one way to think about it is

  • how can I go from zero to 6/10 in two jumps?

  • Two equal jumps, I should say.

  • Well, if we just eyeball it right over here,

  • I could do one jump like that

  • and then another jump like that.

  • So I did one jump and then two jumps.

  • And so one way to think about it is

  • we've divided 6/10 into two jumps,

  • and each of those jumps are how far?

  • Well, each of those jumps are one, two, 3/10.

  • So this is 3/10 or I could write it like this, 3/10.

  • We have another one, two, 3/10.

  • So this is going to be equal to 3/10.

  • And we've thought about it in other ways.

  • If you have six of something and you divide it by two,

  • you're going to have two groups of three of that something.

  • So if you have 6/10, and you wanna

  • put it into two equal groups, well,

  • each of those groups are going to be 3/10.
