(1) 450000 is 5/7 of his interest, which we can call x:

450000+=+%285%2F7%29x
%287%2F5%29%28450000%29+=+%287%2F5%29%285%2F7%29x+=+x
7%2A90000+=+x
x+=+630000

Kimaro's interest in the operation before selling was 630000.

(2) 630000 was 3/5 of the total value of the operation, which we can call x:

630000+=+%283%2F5%29x
%285%2F3%29%28630000%29+=+%285%2F3%29%283%2F5%29x+=+x
5%2A210000+=+x
x+=+1050000

The total value of the operation is 1050000.
