Yesterday and maybe a couple days ago, we have been adding/subtracting basic fractions, with like (same) denominators. Today, we are going learn what to do when our numerator is bigger than our denominator. But first, lets review!!!
5/10 + 3/10 =
3/4 - 2/4 =
14/20 - 11/20 =
Did you get them right? Good Job! Now we are going to learn about two new vocabulary words: Mixed Number and Improper Fraction
Look at the numerator! Do you notice something weird? This is called an Improper fraction. We have more than one whole.
Another way to write 5/4, it to write it as a mixed number (as shown above). Look at the picture above! How many wholes do we see? Now, what is left? Put them together. 1 whole and 1/4 is 1 1/4!
They are both the same! They are just written differently. It is important to know how to write them both ways! Don't worry we will practice and you'll be a pro!
Let's first learn to how to go from Improper fraction to a mixed number!
How many wholes (groups of 3) can fit into 20? Or 20 parts makes how many wholes? If you remember the --- in the fraction also means divide!
Now you try! Look at the example above and rewrite the improper fractions as mixed numbers in your notebook!
How did you do? Did you get the right answer? Are there any questions?!? Ready to try it the other way?
THE DENOMINATOR STAYS THE SAME!!
What do you think? Easy enough? Can you do it? Lets try! Write the following mixed numbers into improper fractions. You can use your fraction kit if you need to.
4 3/5 =
7 5/8 =
10 1/2 =
How did you do? Did you get them write correctly? You guys did awesome today!! I am proud of you!
