Rory spends 1/5 hour cleaning the table,3/10 hour washing dishes, and 4/5 hour reading a book. how many hours does she spend doing all these activities?

She spends an hour and 3/10ths of an hour.
1/5 + 3/10 + 4/5 (Make the denominators the same by finding the least common denominator- which then they would be )  1/10 + 3/10 + 4/10 = 13/10 ( Now covert it to a proper fraction ) = 1  3/10  :)

Iam guessing c. or d.
