1 teaspoon = 5 milliliters 1 teaspoon = 60 drops
fluid ounce 1 = fluid drams 8 1 quart = 1 liter
fluid ounce 1 = 2 tablespoons 1 inch = 2.54 centimeters
fluid ounce 1 = 30 milliliters 1 cubic centimeter = 1 milliliter
3 1/4 inches = □ cm
(type an integer or decimal rounded to the nearest hundredth as needed.)

Explanation:

Step1: Convert the mixed - number to decimal

$3\frac{1}{4}=3 + \frac{1}{4}=3+0.25 = 3.25$

Step2: Use the conversion factor

Since 1 inch = 2.54 centimeters, to convert 3.25 inches to centimeters, we multiply the number of inches by the conversion factor. So, $3.25\times2.54$.
$3.25\times2.54=(3 + 0.25)\times2.54=3\times2.54+0.25\times2.54=7.62+0.635 = 8.255\approx8.26$

Answer:

8.26
