12 1/4= (12x4+1):4= 49/4 inches of rain The number of hours is 2512 So we do the division to find out the approximate rainfall rate in inches per hour: 49/4 : 2512= 0.0049 inches per hours
But I found you wrongly typed the hours 25 1/2= 51/2 If it is true we have the approximate rainfall rate in inches per hour: 49/4 : 51/2= 49/4 x 2/51= 0.48 inches per hour
