As for fractions, the simplest form is considered that in which the numbers in the ratio are the smallest possible integers. Thus, the ratio 40:60 is equivalent in meaning to the ratio 2:3, the latter being obtained from the former by dividing both quantities by 20. Mathematically, we write 40:60 = 2:3, or equivalently 40:60∷2:3.
A repeating decimal or recurring decimal is a decimal representation of a number whose digits are eventually periodic (that is, after some place, the same sequence of digits is repeated forever); if this sequence consists only of zeros (that is if there is only a finite number of nonzero digits), the decimal is said to be terminating, and is not considered as repeating.
A method analogous to piece-wise linear approximation but using only arithmetic instead of algebraic equations, uses the multiplication tables in reverse: the square root of a number between 1 and 100 is between 1 and 10, so if we know 25 is a perfect square (5 × 5), and 36 is a perfect square (6 × 6), then the square root of a number greater than or equal to 25 but less than 36, begins with ...
The fractional excretion of sodium (FE Na) is the percentage of the sodium filtered by the kidney which is excreted in the urine.It is measured in terms of plasma and urine sodium, rather than by the interpretation of urinary sodium concentration alone, as urinary sodium concentrations can vary with water reabsorption.
The hematocrit (/ h ɪ ˈ m æ t ə k r ɪ t /) (Ht or HCT), also known by several other names, is the volume percentage (vol%) of red blood cells (RBCs) in blood, [1] [2] measured as part of a blood test. [3] The measurement depends on the number and size of red blood cells. [3] It is normally 40.7–50.3% for males and 36.1–44.3% for ...
The α form of the tetrahydrate has density 1.33 g/cm 3. It melts congruously at 7.55 °C into a liquid with 35.7% NaOH and density 1.392 g/cm 3 , and therefore floats on it like ice on water. However, at about 4.9 °C it may instead melt incongruously into a mixture of solid NaOH·3.5H 2 O and a liquid solution.
A more precise study was conducted by the local University of the West Indies - Jamaica's population is more accurately 76.3% African descent or Black, 15.1% Afro-European (or locally called the Brown Man or Browning Class), 3.4% East Indian and Afro-East Indian, 3.2% White, 1.2% Chinese and 0.8% Other.
[1]: 91 While the resurgence of conservatism and the Third Way of Bill Clinton's New Democrats briefly weakened the influence of modern liberalism, Barack Obama acted as an ideological bridge. While characterizing himself as a New Democrat, Obama toed the ideological line between the Third Way and modern liberalism.
