Transcript text: An active ingredient is $6.273\%$ of a solution. Which of the following is the fraction of the ingredient in the solution?
$3 / 50$
$3 / 20$
$2 / 3$
$1 / 15$
Solution
Solution Steps
Step 1: Convert the percentage to a decimal
The given percentage of the active ingredient is \(6.273\%\). To convert this to a decimal, divide by 100:
\[
6.273\% = \frac{6.273}{100} = 0.06273
\]
Step 2: Compare the decimal to the given fractions
Now, compare the decimal \(0.06273\) to the decimal equivalents of the given fractions:
\[
\frac{3}{50} = 0.06, \quad \frac{3}{20} = 0.15, \quad \frac{2}{3} \approx 0.6667, \quad \frac{1}{15} \approx 0.0667
\]
Step 3: Identify the closest fraction
The decimal \(0.06273\) is closest to \(\frac{1}{15} \approx 0.0667\). Therefore, the fraction of the ingredient in the solution is \(\frac{1}{15}\).
