#### Ok, but what does this all mean ?

First, let's review dividing whole numbers by whole numbers. (We will soon see that dividing whole numbers by unit fractions has the same meaning.)

$$6 \div 3$$ means: How many groups of 3 are in 6. As you can see, there are 2 groups of 3 in 6.

#### Now, let's look at whole by unit fraction

We can think of 2 divided by $$\frac{1}{4}$$ as "How many $$\frac{1}{4}$$'s are in 2?
