Weegy: A fraction (from the Latin fractus, broken) is a number that can represent part of a whole. [ The earliest fractions were reciprocals of integers: ancient symbols representing one part of two, one part of three, one part of four, and so on.[1] A much later development were the common or "vulgar" fractions which are still used today (?, ?, ?, etc.) and which consist of a numerator and a denominator, the numerator representing a number of equal parts and the denominator telling how many of those parts make up a whole. An example is 3/4, in which the numerator, 3, tells us that the fraction represents 3 equal parts, and the denominator, 4, tells us that 4 parts make up a whole. ] User: define the planet Mars'\ (More)
