Instructions and Help about How Form 2220 Amounts

P>Hi, I'm Rob. Welcome to Math Antics. In this lesson, we're going to learn how to add mixed numbers. If you're not quite sure what mixed numbers are, then you should definitely watch our video called "Mixed Numbers" first. As you remember, a mixed number is a combination or sum of a whole number and a proper fraction. And for this lesson, it's important to remember that even though the plus symbol isn't usually shown between those two parts of a mixed number, they're being added together. 3 and 1/4 means 3 plus 1/4. 2 and 5/8 means 2 plus 5/8. And here's why that's so important to remember. Let's say you're given a problem. We need to add the whole number 2 to the mixed number 3 and 1/4. If you know that 3 and 1/4 is the same as 3 plus 1/4, then you can see that the problem is really 2 plus 3 plus 1/4. Well, that's easy. All you have to do is add the 2 and the 3 to get 5. And you'll have 5 plus 1/4, which is the mixed number 5 and 1/4. So if you need to add a whole number to a mixed number, you can just add the whole number parts and you're done. But what if you need to add a mixed number to a fraction, like in the problem 1 and 3/8 plus 1/8? Again, if you remember that 1 and 3/8 means 1 plus 3/8, then you can see that this problem is really 1 plus 3/8 plus 1/8. That looks pretty easy, too. 3/8 and 1/8 are what we call like fractions. They have the same denominator and can be added easily. 3/8 plus 1/8 equals 4/8. So our answer is simply the mixed number 1 and 4/8....
