Nature: Validity of PSA, free/total PSA ratio and complexed/total PSA ratio measurements in men with acute urinary retention
Validity of PSA, free/total PSA ratio and complexed/total PSA ratio measurements in men with acute urinary retention
The reliability of serum prostate specific antigen (PSA) measurements in men with acute urinary retention is unclear. Total PSA, free and complexed PSA were measured, and the free/total (f/t) PSA and ...

Compare ratios and evaluate as true or false to answer whether ratios or fractions are equivalent. This ratio calculator will accept integers, decimals and scientific e notation with a limit of 15 characters. The calculator will simplify the ratio A : B if possible.
A ratio tells us how much of one thing we have compared to another. There are 3 blue squares to 1 yellow square.
In mathematics, a ratio (/ ˈreɪ.ʃ (i.) oʊ /) shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
A ratio is a simple comparison between two quantities. It says how much one thing is there compared to another. For example, in a group of 7 students, 4 are men and 3 are women. Then, the ratio of men to women is 4:3. In words, it is spelled as for every 3 women, there are 4 men.
