Example 1: Academic Grading
Suppose a student scores 15 points out of a total of 96 points on an exam.
- Percentage score:
\[ \frac{15}{96} \times 100\% \approx 15.63\% \]
- Implication: The student scored approximately 15.63% of the total possible points, indicating a low performance.
Example 2: Inventory and Resources
Imagine a warehouse holding 96 units of a product, and 15 units are allocated to a particular store or department.
- Proportion of total inventory:
\[ \frac{15}{96} = \frac{5}{32} \approx 0.15625 \]
- Interpretation: The store receives roughly 15.63% of the total inventory.
Example 3: Financial Contexts
If an investor owns 15 shares out of a total of 96 shares of a company, the ownership percentage is:
\[ \frac{15}{96} \times 100\% \approx 15.63\% \]
This indicates a significant ownership stake.
Understanding Ratios and Proportions
The expression "15 of 96" can also be viewed through the lens of ratios.
Ratio Representation
The ratio of 15 to 96 is written as:
\[ 15:96 \]
Simplified, as shown earlier, to:
\[ 5:32 \]
This ratio indicates that for every 5 parts of the subset, there are 32 parts of the whole.
Use in Real Life:
- Cooking: If a recipe calls for 5 grams of spice per 32 grams of flour, then the ratio is 5:32.
- Mixing solutions: The ratio of ingredients could be 5 parts to 32 parts.
Interpreting the Ratio
Ratios help understand the relative quantities and are useful for scaling recipes or adjusting proportions.
