Incorrect.
One example is on the bottom row, 1 2 1 wouldn't be valid because their sum is 4. and the shaded square would be the one on the far left, which must be 50% of the sum un that row. 1 is not 50% of 4. It would be 2.
There were a couple more errors too. Is 6 75% of 12? No, it would be 9.
Keep trying!
