Approx 0.9 of an iceberg is submerged.
There is 90% of an iceberg's volume (and mass) that is underwater.
You can't breathe underwater at all.
Approximately 90% of an iceberg lies submerged underwater, while only about 10% is visible above the surface. This phenomenon occurs because ice is less dense than water, causing the majority of the iceberg to float below the waterline. The exact fraction can vary slightly depending on the specific density of the ice and the salinity of the surrounding water.
There cannot be a whole fraction. If it is a fraction it is not whole and if it is whole it is not a fraction.
No, every fraction is not a unit fraction because unit fraction must have 1 as numerator but every unit fraction is a fraction such as 2/3 is a fraction but not considered a unit fraction and 1/3 which is a unit fraction is also called fraction
