To find the fraction that the test counts of the final mark, we need to consider the relationship between the test mark, the year mark, and the final mark.

Let's denote:
- $$ T $$ as the test mark
- $$ Y $$ as the year mark
- $$ F $$ as the final mark

Given:
- The test counts $$ 20\% $$ of the year mark: $$ T = 0.20Y $$
- The year mark counts $$ 25\% $$ of the final mark: $$ Y = 0.25F $$

We need to find the fraction that the test counts of the final mark, which is $$ \frac{T}{F} $$.

Substitute the expressions for $$ T $$ and $$ Y $$ in terms of $$ F $$ into the equation for $$ \frac{T}{F} $$ to find the fraction that the test counts of the final mark.
Simplify the expression by following steps:
- step0: Solution:
  $$0.2	imes 0.25F$$
- step1: Multiply the terms:
  $$0.05F$$
The fraction that the test counts of the final mark is $$ 0.05F $$, which simplifies to $$ \frac{1}{20}F $$.
The test counts $$ \frac{1}{20} $$ of the final mark.

(c) In a certain school, a test counts \( 20 \% \) of the year mark. The year mark counts \( 25 \% \) of final mark. What fraction does the test count of the final mark?
