Every terminating decimal representation can be written as a decimal fraction, a fraction whose denominator is a power of 10 (e.g. 1.585 = 1585 / 1000 ); it may also be written as a ratio of the form k / 2 n ·5 m (e.g. 1.585 = 317 / 2 3 ·5 2 ).
The different decimal numeral systems of the world use a larger base to better envision the size of the number, and have created names for the powers of this larger base. The table shows what number the order of magnitude aim at for base 10 and for base 1 000 000 .
For higher precision, the seconds are specified with a decimal fraction. An alternative representation uses degrees and minutes, and parts of a minute are expressed in decimal notation, thus: 23° 27.5′ E. Degrees may also be expressed as a decimal fraction: 23.45833° E.
It is the same concept as volume percent (vol%) except that the latter is expressed with a denominator of 100, e.g., 18%. The volume fraction coincides with the volume concentration in ideal solutions where the volumes of the constituents are additive (the volume of the solution is equal to the sum of the volumes of its ingredients).
The resulting fraction was multiplied by 100 to obtain the IQ score. [2] For modern IQ tests, the raw score is transformed to a normal distribution with mean 100 and standard deviation 15. [3] This results in approximately two-thirds of the population scoring between IQ 85 and IQ 115 and about 2 percent each above 130 and below 70. [4] [5]
As an example, Canada's net population growth was 2.7 percent in the year 2022, dividing 72 by 2.7 gives an approximate doubling time of about 27 years. Thus if that growth rate were to remain constant, Canada's population would double from its 2023 figure of about 39 million to about 78 million by 2050.
[16] [17] The overall U.S. trade deficit widened 12.2 percent in 2022 to nearly $1 trillion as Americans bought large volumes of foreign machinery, pharmaceuticals, industrial supplies and car parts, according to new data released by the Commerce Department. [18] The US last had a trade surplus in 1975. [19]
French is the mother tongue of approximately 10 million Canadians (22 percent of the Canadian population, second to English at 56 percent) according to the 2021 Canadian Census. [1] Most Canadian native speakers of French live in Quebec , the only province where French is the majority and the sole official language. [ 2 ]
