I was having trouble with this problem. please let me know how to approach this. thanks.

The density of ice is 920 kg/m3, and that of seawater is 1030 kg/m3. What fraction of the total volume of an iceberg is exposed?

Use Archimede's principle. The amount of seawater displaced by the iceberg - the weight of the seawater displaced by the volume of the iceberg below the surface $V_{below}$ - needs to be equal to the weight of all of the iceberg.
