Answer: D.) start fraction 5 over 6 end fraction
Explanation: We can also write negative fractions, which represent the opposite of a positive fraction. For example, if 1/2
represents a half-dollar profit, then −1/2
represents a half-dollar loss. Because of the rules of division of signed numbers (which states in part that negative divided by positive is negative), −1/2, −1/2
and 1/−2 all represent the same fraction – negative one-half. And because a negative divided by a negative produces a positive, −1/−2
represents positive one-half.
In mathematics the set of all numbers that can be expressed in the form a/b, where a and b are integers and b is not zero, is called the set of rational numbers and is represented by the symbol Q, which stands for quotient. A number is a rational number precisely when it can be written in that form (i.e., as a common fraction). However, the word fraction can also be used to describe mathematical expressions that are not rational numbers.
