At boarding school, students spend \(\frac{1}{4}\) of their time eating and sleeping, \(\frac{3}{5}\)of their time in class, and \(\frac{1}{4}\) studying. The rest of the time is considered free time, which the student can spend doing activities of their own choosing. What fraction is considered free time?

\(\frac{1}{15}\)

Explanation

First you need to find a common denominator for these fractions. The common denominated for 4, 5, and 12 is 60. The fractions convert accordingly to: \(\frac{15}{60}\), \(\frac{36}{60}\), \(\frac{5}{60}\).
Now add these three fractions:
\(\frac{15}{60}+ \frac{36}{60} + \frac{5}{60} = \frac{56}{60}\).
Compute for the time left by subtracting 56/60 from the fraction representing the whole day 60/60:
\(\frac{60}{60} - \frac{56}{60} = \frac{4}{60} = \frac{1}{15}\) (Reduced to the lowest terms)
