In this section, we'll provide examples and step-by-step explanations to ensure you can confidently perform these calculations.

Example 1: Converting 3 Tablespoons to Milliliters

Let's start with the scenario presented in the original question: determining the approximate number of milliliters in 3 tablespoons. To do this, we simply multiply the number of tablespoons (3 tbsp) by the conversion factor (15 mL/tbsp):

3 tbsp * 15 mL/tbsp = 45 mL

Therefore, there are approximately 45 milliliters in 3 tablespoons.

Example 2: Converting 5 Tablespoons to Milliliters

Similarly, to convert 5 tablespoons to milliliters, we perform the following calculation:

5 tbsp * 15 mL/tbsp = 75 mL

Thus, 5 tablespoons is equivalent to approximately 75 milliliters.

Example 3: Converting 10 Tablespoons to Milliliters

For a larger quantity, such as 10 tablespoons, the calculation remains the same:

10 tbsp * 15 mL/tbsp = 150 mL

Therefore, 10 tablespoons contains approximately 150 milliliters.

General Formula

To generalize this process, we can use the following formula:

Milliliters (mL) = Number of Tablespoons (tbsp) * 15 mL/tbsp

This formula provides a simple and reliable method for converting any number of tablespoons to milliliters. By understanding this formula and the underlying conversion factor, you can confidently handle various measurement conversions in your culinary endeavors and beyond.

Choosing the Correct Expression for Conversion

When presented with conversion problems, it's crucial to select the correct expression that accurately reflects the conversion process. The options provided in the original question highlight the importance of understanding how units cancel out during calculations. Let's analyze each option to determine the correct expression for converting tablespoons to milliliters.

Option A: 1 tbsp × (15 mL / 3 tbsp)

This expression is incorrect because it attempts to divide the desired milliliters by the number of tablespoons. This approach does not align with the fundamental conversion principle of multiplying the number of tablespoons by the conversion factor (15 mL/tbsp). Additionally, the units do not cancel out correctly in this expression, leading to an incorrect result.

Option B: 1 tbsp × (3 mL / 15 tbsp)

This expression is also incorrect. It uses an inverted conversion factor (3 mL / 15 tbsp), which would result in a value smaller than 1 mL, which does not make sense when converting tablespoons to milliliters. Again, the units do not cancel out appropriately, indicating an error in the expression.

Option C: 3 tbsp × (15 mL / 1 tbsp)

This is the correct expression for finding the approximate number of milliliters in 3 tablespoons. It correctly multiplies the number of tablespoons (3 tbsp) by the conversion factor (15 mL / 1 tbsp). Notice how the units of "tbsp" cancel out, leaving the final answer in milliliters (mL), which is the desired unit.

3 tbsp * (15 mL / 1 tbsp) = 45 mL

Key Principle: Unit Cancellation

The correct expression demonstrates the crucial principle of unit cancellation in dimensional analysis. By ensuring that the units cancel out appropriately, you can verify the accuracy of your conversion calculations. In this case, the "tbsp" units in the numerator and denominator cancel out, leaving the result in "mL," which is the desired unit for the answer.
