| has gloss | (noun) the relative magnitudes of two quantities (usually expressed as a quotient)
ratio |
| has gloss | eng: A ratio between two quantities A and B is their fraction A/B. A ratio is a mathematical way of expressing the proportion of A to B. For example, if I bought 20 apples and have only 9 left, what is the proportion (or ratio) of 9 to 20? The answer is 9/20 or 0.45/1. The ratio may also be written as 0.45. Ratios can be changed into percentages, fractions and decimals. |
| has gloss | eng: In mathematics, a ratio expresses the magnitude of quantities relative to each other. Specifically, the ratio of two quantities indicates how many times the first quantity is contained in the second and may be expressed algebraically as their quotient. Example: For every Spoon of sugar, you need 2 spoons of flour ( 1:2 ) |
