Let's solve the problem step by step using
visual reasoning and
mathematical understanding of dividing unit fractions by whole numbers.

🔍 Understanding the Concept:
We are dividing a
unit fraction (like $ \frac{1}{3}, \frac{1}{4} $, etc.) by a
whole number.
For example:
$$
\frac{1}{3} \div 4 = ?
$$
This means: *If you have one-third of a whole, and you divide that third into 4 equal parts, how big is each part?*
Visually, this can be shown by:
1. Starting with a whole.
2. Dividing it into 3 equal parts (to get $ \frac{1}{3} $).
3. Then taking just
one of those thirds and splitting it into 4 equal pieces.
4. Each small piece is $ \frac{1}{12} $ of the original whole.
So:
$$
\frac{1}{3} \div 4 = \frac{1}{12}
$$
In general:
$$
\frac{1}{a} \div b = \frac{1}{a \times b}
$$

✔ Solutions with Explanation
#### 1) $ \frac{1}{3} \div 3 = ? $
- Divide $ \frac{1}{3} $ into 3 parts → each part is $ \frac{1}{9} $
- So: $ \frac{1}{3} \div 3 = \frac{1}{9} $
✔ Answer: $ \boxed{\frac{1}{9}} $
---
#### 2) $ \frac{1}{8} \div 8 = ? $
- Take $ \frac{1}{8} $ and split it into 8 equal parts.
- Each part is $ \frac{1}{64} $
- So: $ \frac{1}{8} \div 8 = \frac{1}{64} $
✔ Answer: $ \boxed{\frac{1}{64}} $
---
#### 3) $ \frac{1}{7} \div 2 = ? $
- Split $ \frac{1}{7} $ into 2 parts → each is $ \frac{1}{14} $
- So: $ \frac{1}{7} \div 2 = \frac{1}{14} $
✔ Answer: $ \boxed{\frac{1}{14}} $
---
#### 4) $ \frac{1}{3} \div 4 = ? $
- As in the example: $ \frac{1}{3} \div 4 = \frac{1}{12} $
✔ Answer: $ \boxed{\frac{1}{12}} $
---
