Answer :

To convert [tex]\( \frac{1}{2} \)[/tex] cup to milliliters, we need to know the conversion factor between cups and milliliters.

1 cup is equivalent to 240 milliliters.

Since we want to convert half a cup, we need to find half of 240 milliliters.

Step-by-Step Solution:

1. Start with the conversion factor:
[tex]\[ 1 \text{ cup} = 240 \text{ milliliters} \][/tex]

2. We need to find [tex]\( \frac{1}{2} \)[/tex] cup in milliliters, which is also written as:
[tex]\[ \frac{1}{2} \text{ cup} \][/tex]

3. Calculate half of 240 milliliters:
[tex]\[ \frac{1}{2} \times 240 \text{ milliliters} \][/tex]

4. Perform the multiplication:
[tex]\[ 0.5 \times 240 = 120 \text{ milliliters} \][/tex]

Therefore, [tex]\( \frac{1}{2} \)[/tex] cup is equal to 120 milliliters.

So, the correct option is:
d. 120 mL.
