What do combined fractions favor 2-3/5 and also 5-7/8 look at like as soon as written together improper fractions? just how do you easily convert between these two workhorses of the fraction world? review on to find out!

Hot ~ above the heels of our first foray right into the always exciting people of blended fractions, this mainly we’re walk to run right earlier into that topic and also clean up a couple of rough edges. In particular, after ~ a quick review that the stuff we learned last time—namely what proper, improper, and also mixed fountain are and also how to rotate improper fractions into mixed fractions—today we’re going to talk about how you deserve to turn every one of those combined fractions you’ve just created earlier into wrong fractions. Why would certainly you desire to carry out that? That’s a great question! and it’s specifically the question we’ll be answering over the next couple of weeks.

You are watching: 8/3 as a mixed number

## How come Turn mixed Fractions right into Improper Fractions

Now the we’ve had some exercise converting wrong fractions right into mixed fractions, you could be wondering just how to walk the various other way. In various other words, how do you undo whatever we’ve done and convert a mixed portion back right into an not correct fraction? The trick is to begin by multiplying the entirety number part of the mixed fraction by the denominator that the proper fraction part. Because that the fraction 2-1/4, that method you first need to multiply 2 (the whole number part) by 4 (the denominator that the proper portion part) to find that 2 x 4 = 8. Next, add this number to the molecule of the proper fraction part. For 2-1/4, that method we need to include the number we got—which to be 8—to the molecule 1 to get 8 + 1 = 9. This number is in reality the numerator of the improper portion you’re seeking. What’s its denominator? It’s just the denominator the the proper portion part the the original mixed fraction. So because that 2-1/4, it’s 4. Which means that the mixed fraction 2-1/4 is indistinguishable to the improper fraction 9/4.How around the mixed portion 4-2/3? Well, the first step is to multiply its totality number part—that’s the 4—by the denominator of its proper portion part—that’s the 3—to get 4 x 3 = 12. Next, add this number come the molecule of the proper portion part—that’s the 2—to get 12 + 2 = 14. Finally, we compose this number end the denominator of the proper portion part the 4-2/3—that’s the 3—to discover that the mixed fraction 4-2/3 is equivalent to the improper fraction 14/3.

## Why go this switch Work?

At this point, this all type of looks prefer some kind of magic trick, right? while I gain magic, I never enjoy making mathematics look choose magic…because it’s crucial to remember the it’s not! therefore let’s take a minute to number out exactly what’s going on. First, let’s think about what a mixed fraction like 2-1/4 yes, really means. Notice that 2-1/4 is really simply another way of writing 2 + 1/4. In various other words, together we’ve talked around before, every mixed portion is the sum of a whole number and a suitable fraction. For reasons that will end up being clear in a moment, let’s rewrite the number 2 here as the fraction 2/1. And then, simply for fun, let’s create the two fractions in the sum 2/1 + 1/4 in terms of their lowest typical denominator. I beg your pardon is…? Well, together you should examine for yourself, the lowest usual denominator of 2/1 and 1/4 is 4.Okay, let’s now write these fractions in terms of this lowest common denominator. Since 1/4 is currently in regards to it, us only have to worry about finding the equivalent of 2/1. One way to perform that is to main point its top and also bottom through 4 to gain the equivalent portion 8/4. So the mixed portion 2-1/4 can be rewritten together 8/4 + 1/4. Since the denominators of these fractions are the same, all we need to do to add them increase is add their numerators and write the an outcome over their common denominator. What walk this tell us? the tells us that the mixed fraction 2-1/4 is equivalent to the improper fraction 9/4. Look familiar? it should since it’s precisely the same answer we acquired before. Which way that the trick for turning mixed fractions into improper fractions yes, really isn’t a trick in ~ all—it’s just a speedy means of rewriting certain fractions in regards to their lowest common denominator and adding them up. Once again, it’s not magic…it’s math!

## Why transform Mixed Fractions right into Improper Fractions?

But the concern still remains: Why perform we have to bother with any of this counter stuff? Can’t we just leave all the fountain in our resides alone and let them stay in the same blended or improper kind that we discover them in? as we briefly touched upon critical time, the prize is that although we never ever absolutely have actually to convert from one kind of portion to another, law so deserve to make life a lot of easier. Why? since many problems are much less complicated to solve as soon as the fountain in them are written in their improper form. What kind of problems? Well, regrettably we’re all out of time for today. For this reason the answer to that inquiry is walk to have to wait until following time.
