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, 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, 31.32 percent is equal to 783/2500 or seven hundred and eighty-three 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.
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.
35.4 percent expressed as an decimal is 0.354
