Answer :
To find the approximate number of milliliters in 3 tablespoons, we know that 1 tablespoon is approximately 15 milliliters. Therefore, we need to multiply the number of tablespoons by the number of milliliters per tablespoon.
Here's how you can break it down step-by-step:
1. Identify the conversion factor: There are 15 milliliters in 1 tablespoon.
2. Determine the number of tablespoons: We are interested in converting 3 tablespoons.
3. Set up the expression: To find the total milliliters, multiply the number of tablespoons by the conversion factor:
[tex]\[
\text{Approximate milliliters} = \text{Number of tablespoons} \times \text{Milliliters per tablespoon}
\][/tex]
4. Perform the calculation:
[tex]\[
3 \text{ tablespoons} \times 15 \text{ milliliters per tablespoon} = 45 \text{ milliliters}
\][/tex]
5. Expression to use: From the options given, the correct expression that matches this calculation process is:
[tex]\[
3 \text{ thsp} \times \frac{15 \text{ mL}}{1 \text{ tbsp}}
\][/tex]
Therefore, the approximate number of milliliters in 3 tablespoons is 45 mL, and the expression that can be used is [tex]\(3 \text{ thsp} \times \frac{15 \text{ mL}}{1 \text{ tbsp}}\)[/tex].
