jerry is a judge. He hears 5 cases every 2 3/8 hours. Jerry hears caese at a constant rat. How many cases does he hear per hour
faust18 [17]

Answer:

The number of cases heard by Jerry per hour is 2\frac{21}{500}

Step-by-step explanation:

The rate of hearing the cases is 5 cases in 2 3/8 hours.

Now, 2\frac{3}{8}   = 2+\frac{3}{8}  = 2 + 0.375 = 2.375

⇒The judge hears 5 cases in 2.375 hours.

So, the number of cases per hour = = \frac{\textrm{Total Number of cases heard}}{\textrm{Number of Hours}}  = \frac{5}{2.375}

                                                           = 2.105

Also, 2.105 =   2 + 0.105 =  2 + \frac{105}{1000}   = 2+\frac{21}{500}  = 2\frac{21}{500}

Hence, the number of cases heard by Jerry per hour is 2\frac{21}{500}
