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

To determine the approximate number of milliliters (mL) in 3 tablespoons (tbsp), you need to use the conversion factor that relates milliliters to tablespoons. The conversion factor given is that 1 tablespoon is approximately equal to 15 milliliters.

Here's a step-by-step breakdown to find the correct expression:

1. Identify the conversion factor: You are given that 1 tbsp = 15 mL.
2. Set up the expression: To convert tablespoons to milliliters, you multiply the number of tablespoons by the conversion factor.

- You have 3 tablespoons.
- The conversion factor is [tex]$\frac{15 \text{ mL}}{1 \text{ tbsp}}$[/tex].

3. Write the expression: Multiply the number of tablespoons (3 tbsp) by the conversion factor ([tex]$\frac{15 \text{ mL}}{1 \text{ tbsp}}$[/tex]):
[tex]\[ 3 \text{ tbsp} \times \frac{15 \text{ mL}}{1 \text{ tbsp}} \][/tex]

4. Simplify the units: The tablespoons (tbsp) in the numerator and denominator cancel each other out:
[tex]\[ 3 \times 15 \text{ mL} \][/tex]

5. Calculate the result: Finally, perform the multiplication:
[tex]\[ 3 \times 15 = 45 \text{ mL} \][/tex]

So, the correct expression to find the approximate number of milliliters in 3 tablespoons is:
[tex]\[ 3 \text{ tbsp} \times \frac{15 \text{ mL}}{1 \text{ tbsp}} \][/tex]
