    For example, say a board has 7 members. "Majority" means "at least 4" in this case (more than half of 7). But 50% + 1 is 4.5, and since a number of people can only be integer, "at least 50% + 1" would mean "at least 5". An example of the expression's use to refer to a majority is the 50+1 rule. See also. Majoritarianism; Majority function

    The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel ( B ). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 10 1/10 (approximately 1.26) or root-power ratio of 10 1/20 (approximately 1.12 ).

For instance, the NWS might describe a precipitation forecast with terms such as "slight chance" meaning 20% certainty and "scattered" meaning 30–50% areal coverage. The precise meaning of these terms varies.

    Mass fraction (chemistry) In chemistry, the mass fraction of a substance within a mixture is the ratio (alternatively denoted ) of the mass of that substance to the total mass of the mixture. [1] Expressed as a formula, the mass fraction is: Because the individual masses of the ingredients of a mixture sum to , their mass fractions sum to unity:
