What I did to find the height of the iceberg above water was I took 75 and divided by 9 and I got 8.3.

I took 8.3 repeating and rounded it and got 8.

So 8\9 was 75.

8. 1

- / 8 = -

9. 9

And

75.8/ 8 = 9.475

And when I round it to the nearest tenth it would be 9.5

So the height of the iceberg above water is 9.5.
