21. A chemist has a certain number of containers of liquid. Each container is labeled with the number of fluid ounces of liquid it contains. The chemist is assigning a lab assistant the task of labeling each container with the number of cups of liquid it contains. Which of the following formulas should the chemist give to the lab assistant to use for the task?

A. cups [tex]=0.125 \times[/tex] (fluid ounces)
B. cups [tex]=8 \div[/tex] (fluid ounces)
C. cups [tex]=8 \times[/tex] (fluid ounces)
D. cups [tex]=8+[/tex] (fluid ounces)
E. cups [tex]=[/tex] (fluid ounces [tex])-8[/tex]



Answer :

To solve this problem, we need to convert fluid ounces into cups. We know that:

1 cup = 8 fluid ounces

Therefore, to convert fluid ounces to cups, we need to find out how many cups are in one fluid ounce. To do this, we divide 1 cup by 8 fluid ounces:

[tex]\[ \text{1 fluid ounce} = \frac{1 \text{ cup}}{8} = 0.125 \text{ cups} \][/tex]

This means that each fluid ounce is equivalent to 0.125 cups. To convert any given number of fluid ounces to cups, we multiply the number of fluid ounces by 0.125. Therefore, the correct formula for converting fluid ounces to cups is:

[tex]\[ \text{cups} = 0.125 \times (\text{fluid ounces}) \][/tex]

Thus, the correct answer is:

A. cups [tex]$=0.125 \times$[/tex] (fluid ounces)
