How To Convert Mixed Numbers To Improper Fractions (Concrete And Pictorial)

Hi, I'm Brooke, and in this video we're going to be converting mixed numbers to improper fractions. Now, an improper fraction is where the numerator is equal to or greater than the denominator. So let's have a look at this example. I've got two and a half apples and I want to convert it into an improper fraction. So I'm going to start by identifying the denominator, which is two. I'm going to divide each of my wholes into two equal parts. So now I can see that I've got 1, 2, 3, 4, 5 halves, which can be written as 5 over 2. Let's have a look at another example here I've got three and three quarter pizzas. I'm going to identify the denominator, which is four, and divide my wholes into four equal parts. Now we can see that I've got four, eight, twelve quarters. And then I'm going to add on my remaining fractional part, which is three quarters. And remember that when we're adding fractions, the denominator stays the same and we just need to add the numerator which gives us 15 quarters. And we can see that 15 quarters is equivalent to three and three quarters. And that's how you convert a mixed number to an improper fraction.
