Question

use the following chart to do the conversion of $3\frac{1}{4}$ cups = fluid ounces
approximate equivalents
1 teaspoon = 5 milliliters
1 kilogram = 2.2 pounds
grain i = 60 milligrams
1 teaspoon = 60 drops
grain i = 1 drop
1 quart = 1 liter
fluid ounce 1 = 6 teaspoons
1 pint = 2 cups
fluid ounce 1 = 2 tablespoons
1 quart = fluid ounces 32
fluid ounce 1 = 30 milliliters
1 gram = grains 15
1 inch = 2.54 centimeters
1 cup = 240 milliliters
$3\frac{1}{4}$ cups = fluid ounces
(round to the nearest whole number as needed.)

Explanation:

Step1: Convert the mixed number to an improper fraction

$3\frac{1}{4}=\frac{3\times4 + 1}{4}=\frac{13}{4}$ cups.

Step2: Use the conversion factor

Since \(1\) cup \( = 240\) milliliters, then \(\frac{13}{4}\) cups \(=\frac{13}{4}\times240\) milliliters.

Step3: Convert milliliters to fluid ounces

Since \(1\) fluid ounce \( = 30\) milliliters, then the number of fluid ounces \(n=\frac{780}{30}\)

$$ n=\frac{780}{30}=26 $$

Answer:

\(26\)
