real life connect of ratio and proportion

Ratio and proportion are mathematical concepts that have practical applications in various real-life scenarios. Here are a few examples where these concepts are used:

### 1. **Cooking and Recipes:**
   - **Ratios** are crucial when adjusting recipes. For instance, if a recipe calls for 2 cups of flour for every 1 cup of sugar, and you want to double the recipe, you need to maintain the same ratio (2:1) by using 4 cups of flour and 2 cups of sugar.

### 2. **Financial Planning:**
   - **Proportions** are often used in budgeting and financial planning. For example, if you know that 20% of your monthly income is spent on rent, and your income increases, you can use proportions to determine how much more you can afford to spend on rent without exceeding the same percentage.

### 3. **Map Reading and Scale:**
   - When reading a map, **ratios** help understand distances. A map might use a scale of 1:100,000, meaning 1 unit on the map corresponds to 100,000 units in real life. This ratio helps in calculating actual distances between places.

### 4. **Mixing Solutions in Chemistry:**
   - **Proportions** are used to mix chemical solutions. For example, if a scientist needs to prepare a solution of 1:4 acid to water, they use 1 part acid for every 4 parts of water. This proportion ensures the solution has the desired concentration.

### 5. **Design and Architecture:**
   - **Ratios** are important in design, especially when maintaining proportions in scale models. Architects often use ratios to create scale models of buildings, ensuring that every aspect of the model is proportional to the real structure.
