#### Explanation:

We start with

#### Answer:

#### Explanation:

Hold the thought for a moment that when you apply the process of, say,

Now consider a fraction (rational number). We have the structure of:

Using the proper names for these we have:

Size indicator tells you how many of what you are counting are needed to make a whole of something (a complete 1)

So

For

For

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Ok! Lets go back to

Write this as

The denominators (size indicators) are the same so we can

,...............................................................................................................

So if you wish to add subtract the counts you need to make the size indicators the same. Otherwise you are trying to do the equivalent operation as the following example.

You need to convert the size indicator of "box of apples" to the size indicator of "single apples" before you can determine how many apples you are left with.

Subtract

But

The size indicators (denominators) are the same so we can directly subtract the counts.

But

#### Answer:

#### Explanation:

Fractions are numbers which many students find difficult to work with. Luckily with equations which have fractions, we can get rid of any fractions immediately by a multiplying by the LCM of the denominators. (same as the LCD)

Note that: if you multiply a fraction by a multiple of the denominator, the denominator can cancel.

For example:

In this question both the denominators are 4

.

Multiply the WHOLE equation by 4
