So, how do you find ruler fractions? Hi. I'm Jimmy Chang. I've been teaching college math for nine years. And we're here to discuss how you can use rulers to write fractions. And it all depends on the kind of ruler that you have. But once you know what kind of units you want, just make sure the ruler has enough of what we call marks or ticks on the rulers that you can go for the fractions that you're looking for. Now, depending on the ruler, you can work with halves, quarters, eights and sixteenths. So, for the purposes of this demonstration, we'll be looking with rulers with sixteen ticks. Now, let's take a look at, for example, the area between 4 and 5. If you count the area between 4 and 5, you'll discover that there's sixteen ticks. So, that means for each tick, it represents a sixteenth of an increase. So, for example, if you take a look at this very first one here, that represents 4 and 1/16. Two ticks, 4 and 2/16, but you can use these as opportunities to teach students to reduce fractions. Because, as you know, with 2/16, you can reduce both of these by 2. This will be 4 and 1/8. Now, three ticks will give you 4 and 3/16. Four ticks will give you 4 and 4/16. But, as you know, you can teach the students that four and sixteen reduces to 4 and 1/4. And then, you can do it for any number of ticks that you want between whole numbers, even at the halfway mark. At the halfway mark, you know there's eight ticks in between 4 and 5. So, this will be 4 and 8/16, which you can reduce to 4 and 1/2, because both sides are reducible by 8. But, you can use a ruler at any point and use any number of ticks that you're looking for and you can convert into any fraction or mixed number that you like and students will learn fractions in a very straight forward manner. So, I'm Jimmy, and that's how you learn ruler fractions.
