Answer:

1)
= 10 (2)/(5) = (52)/(5)

2)
= (252)/(25) = 10 (2)/(25)

Explanation:


6 (4)/(5) + 3 (3)/(5) \\ (6 + 3) + ( (4)/(5) + (3)/(5) ) \\ 9 + (7)/(5) = 9 + 1 (2)/(5) \\ 9 + 1 + (2)/(5) = 10 + (2)/(5)


\boxed{\green{= 10 (2)/(5) = (52)/(5)}}

•◇•◇•◇•◇•◇•◇•◇•◇•◇•◇•


2 (4)/(5) * 9 (2)/(5) \\ (14)/(5) * 9 * (2)/(5 )


\boxed{\green{ = (252)/(25) = 10 (2)/(25)}}
