Adding and Subtracting Fractions With Unlike Denominators

Watch the video on the link below.  It is not necessary to watch the whole thing!

Stop at 1:47

Two important things:

2. If your answer is an improper fraction like 7/3, you should make it a mixed number

7/3 = 2 and 1/3.    Link below for review

Here’s the explanation in words:

Remember, when we add or subtract fractions, the denominators must be the same.

¼  + ¾ = 4/4   In simplest form, that equals 1

The denominators are the same, so all we have to do is add the numerators.
-------------------------------------------------------------------------------------------------------------------------------
When the denominator is not the same, we need to make an equivalent fraction & find the Common Denominator.

½+ ¼ =

Look at the denominators.
Pick the larger one, and that will be the common denominator.  4
Now, find the equivalent fraction, which you know how to do!

½= ?/4     what times 2 = 4 ?     2x2=4 so we also need to multiply the numerator by 2 2x1=2

½=2/4      Now, we have two fractions with common denominators, andwe can easily add them.

2/4 + ¾  = 12/4

Today, we will practice subtracting fractions with like denominators.

Here's how - also explained on page 298 of your text.

1) Subtract the numerators and write the like denominators.

7         3          4
--   -    --   =   --
8         8          8

2) Simplest form

4                                          1
--   divide by the GCF  4  =  --
8                                          4

Factors of 4 = 1, 4, 2
Factors of 8 = 1, 8, 2, 4

Here is a clip from Khan Academy to review simplest form.

Ordering Fractions

If the Denominators are the same, you can easily compare the numerators.

If the denominotors are not the same, you will have to make an equivalent fraction like Tuesday and Wednesday.

When all of the denominators are the same, you will be able to put the fractions in order.

You will be ordering from least to greatest as well as greatest to least
