Because the proportion of dissolved substances in seawater is such a small number, oceanographers typically express salinity in parts per thousand.
The average ocean salinity is around 3.5%. It is typically measured in parts per thousand (ppt) or in PSU (practical salinity units), with most oceans having a salinity close to this average value.
On average, seawater in the world's oceans has a salinity of ~3.5%, or 35 parts per thousand.
Expressed as a decimal fraction, 7 percent of 3000 is equal to 0.07 x 3000 = 11.538461 recurring (that is, 11.538461538..)
A percentage is expressed as a decimal. 100% would be expressed as 1.0 3% (3/100) would be expressed as 0.03 3% of 10,000 = 0.03 x 10,000 = 300
1.46 percent is expressed as 1.46%.
The freshwater biome has a salinity of 0.05 percent or less, making it a low-salinity environment that is home to various species of plants and animals adapted to living in such conditions.
Expressed as a proper fraction in its simplest form, 31.32 percent is equal to 783/2500 or seven hundred and eighty-three two thousand five hundredths.
Expressed as a proper fraction in its simplest form, 16.33 percent is equal to 1633/10000 or one thousand six hundred and thirty-three ten thousandths.
Expressed as a proper fraction in its simplest form, by multiplying the numerator and denominator by 25, 69.24 percent, or 69.24/100, is equal to 1731/2500 or one thousand seven hundred and thirty-one two thousand five hundredths.
70% to 82%
The amount of salinity that there is in the sunlight zone is about 3.5 percent. About 90 percent of sea life also resides in this zone.
35.4 percent expressed as an decimal is 0.354
