4-2 3/4= 1 1/4 (amount of water that rained into the gauge)
1 1/4= 5/4=10/8
10/8 divided by 1/8 = 10
So the rain lasted 10 hours
4-2 3/4= 1 1/4
                         1 1/4= 5/4=10/8
                                                     10/8 divided by 1/8 = 10
                                                                                             rain lasted 10 hours
