During a heavy rainstorm a city in florida received 12 ¼ inches of a rain in 25 ½ hours. what is the approximate rainfall rate in inches per hour?

1) first step

in this exercise you  must  add 12 + 1/4  = 49/4

and  25+1/2 = 51/2

2) second step

now you must express the fraction inches of rain /hours

49/4÷51/2 = 49/102 , it means  49 inches of  rains/ 102 hours

No solution

Explanation:

-4+19-7f = -15-7

cancel terms on both sides ( add 7f on both sides)

Calculate the sum

-4+19= -15

-4+19=15

15 = -15

The statement 15 = -15 is false so there is no solution :)
