Full solution

Q. Jerry is a judge. He hears 55 cases every 238 2 \frac{3}{8} hours. Jerry hears cases at a constant rate.\newlineHow many cases does he hear per hour?\newlinecases per hour
  1. Convert to Improper Fraction: Convert the mixed number 2382\frac{3}{8} hours to an improper fraction to simplify calculations.\newline2382\frac{3}{8} hours = 2×8+38=16+38=198\frac{2 \times 8 + 3}{8} = \frac{16 + 3}{8} = \frac{19}{8} hours.
  2. Calculate Rate per Hour: Calculate the rate at which Jerry hears cases per hour by dividing the total number of cases by the total hours.\newlineJerry hears 55 cases every 198\frac{19}{8} hours, so the rate is 55 cases per 198\frac{19}{8} hours.\newlineTo find the number of cases per hour, divide 55 by 198\frac{19}{8}.\newlineCases per hour = 5÷(198)=5×(819)=40195 \div (\frac{19}{8}) = 5 \times (\frac{8}{19}) = \frac{40}{19}.\newline4019\frac{40}{19} cases per hour is the rate at which Jerry hears cases.
