The image you provided contains an example of algebraic fractions. Here's what it displays:

1. The notation on the left side shows a simple fraction:

\[
\frac{a}{c} \div \frac{b}{d}
\]

This looks like a proportion or division of two fractions, but the details are not fully written out in the image.

2. The equation on the right side expresses a value \( S \) as:

\[
S = \frac{a}{a + c}
\]

This represents \( S \) as the ratio of \( a \) to the sum of \( a \) and \( c \).

If you want more help with this equation, feel free to ask! Would you like details on solving or interpreting these equations further?

Here are five questions that might help you think further:
1. How do you calculate the result of dividing two fractions like \(\frac{a}{c} \div \frac{b}{d}\)?
2. What is the significance of the expression \( S = \frac{a}{a + c} \)?
3. Can you relate this equation to real-world situations, like probability or ratios?
4. What happens to \( S \) as \( a \) increases, and how does it behave when \( c \) increases?
5. How would you solve for \( a \) if you knew \( S \) and \( c \)?

**Tip:** When dividing fractions, remember that \(\frac{a}{c} \div \frac{b}{d} = \frac{a}{c} \times \frac{d}{b}\). This simplifies many fraction problems!

The image shows a mathematical expression involving algebraic fractions. The left side is a division of fractions (a/c ÷ b/d), and the right side defines S as the ratio of a to the sum of a and c (S = a / (a + c)).
