Question

use the following chart to do the conversion of grain \\( \frac { 1 } { 2 } = \\) _ milligrams. 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 grain \\( \frac { 1 } { 2 } = \square \\) milligrams (round to the nearest whole number as needed.)

Explanation:

Step1: Identify the conversion factor

From the chart, \(1\) grain \( = 60\) milligrams.

Step2: Calculate for \(\frac{1}{2}\) grain

If \(1\) grain \(=60\) milligrams, then for \(\frac{1}{2}\) grain, we use the formula \(x=\frac{1}{2}\times60\).

$$x = \frac{60}{2}=30$$

Answer:

\(30\)
