------------------------------------------------ There are approximately 15 milliliters (mL) in 1 tablespoon (tbsp).

Which expression can be used to find the approximate number of milliliters in 3 tbsp?

A. 1 tbsp [tex]\(\times \frac{15 \text{ mL}}{3 \text{ tbsp}}\)[/tex]

B. 1 tbsp [tex]\(\times \frac{3 \text{ mL}}{15 \text{ tbsp}}\)[/tex]

C. 3 tbsp [tex]\(\times \frac{1 \text{ tbsp}}{15 \text{ mL}}\)[/tex]

D. 3 tbsp [tex]\(\times \frac{15 \text{ mL}}{1 \text{ tbsp}}\)[/tex]

To find the approximate number of milliliters in 3 tablespoons, we need to use the conversion factor given, which is 15 milliliters per 1 tablespoon.

Here's how you can solve the problem step-by-step:

1. Identify the Conversion Factor: We know that 1 tablespoon is approximately equal to 15 milliliters.

2. Set Up the Expression: We want to find the number of milliliters in 3 tablespoons. We use the conversion factor in such a way that tablespoons will cancel out, leaving us with milliliters.

3. Write the Expression: Based on the options provided, the correct expression to use is:
- [tex]\(3 \text{ tbsp} \times \frac{15 \text{ mL}}{1 \text{ tbsp}}\)[/tex]

4. Perform the Calculation:
- Multiply the number of tablespoons (3) by the conversion factor (15 mL per tbsp):
- [tex]\(3 \times 15 = 45\)[/tex]

So, the approximate number of milliliters in 3 tablespoons is 45 milliliters.
