A real number is any comprehendable number, from negative infinity to positive infinity. A rational number is any number that can be the answer to a division equation; an integer, fraction, or a decimal. An irrational number is any number that cannot be expressed as a fraction; such as exponents. Since fractions can also be negative numbers, we cannot necessarily say whether a negative number or a fraction is greater, however, any positive fraction is greater than any negative number.
It is either a positive or negative proper fraction, 0 or an improper negative fraction. You can write it as a fraction. Yes, a fraction can be negative, e. You do not do anything. An improper fraction IS a real number. A fraction is just a number. It's as real as any whole number or decimal. A rational number is simply a number that can be expressed as a fraction, with integer numerator and denominator. Such a number can be positive, negative, or zero.
It belongs to the set of negative rational numbers, negative real numbers, fractionall numbers, rational numbers, real numbers. Some real numbers can be expressed as a rational fraction. Log in.

Is a negative fraction a rational number? But this is not the only option…. Recall how equivalent fractions are created: multiply the original fraction by a fraction that equals one, where numerator and denominator have the same value. If we multiply the above result by 1 in the form of a negative one divided by itself to create another equivalent fraction:. Summarizing these equivalent fraction results:. As long as there is only one negative sign, either in front of the fraction, or in the numerator, or in the denominator, the fraction represents a negative quantity.
As the examples above illustrate, you are welcome to move the negative sign around from where it is to either of the other two positions… whichever is most convenient for you. If there are two fractions being subtracted, and you move the subtraction sign into the numerator or denominator of the fraction being subtracted, put a plus sign where the subtraction sign was subtracting is the same as adding a negative :.
However, note that the negative sign must be applied to the entire numerator, or the entire denominator. So, in cases with more than one term in the numerator or denominator, the negative sign will have to be distributed if it is moved to the numerator or denominator:.
If the last step in the above two examples surprised or puzzled you, my post on Negative Differences may help clear up the confusion. If you have other questions like the one at the top of this post , please ask them in a comment! If I am interpreting your question correctly, you are asking where the -1 came from in the second line of the first example above.
There are a couple of principles involved:. Therefore, a factor of 1 can be introduced into ANY product without changing the result, or any number can be represented as the product of 1 and itself. Additive opposites always add to zero. Added together they result in a sum of zero. Thinking in terms of a number line, a number and its negative will always be on opposite sides of zero, and at equal distances from zero.
If I negate a number twice, it flips to the other size of zero twice, which puts it right back where it started. So, if it is subtraction and a negitive has a around it, it flips to addition and it turns positive? The parentheses are only there to help clarify things. Two negative signs in a row cancel each other out, with or without parentheses, as long as no other variable or number is between the two negatives:.
If so, why negative numbers is used in fractions. Negative sign on a fraction help. Very short and simple. God Bless! Or are you asking about a situation that has multiple terms, one of which is a negative fraction? I think this would affect the slope majorly but I am not sure, I was wondering if it would affect it and how would one know which number the negative sign is on whether the 3 or the 5.
Now start from 5, -3 , and this time put the negative sign by the 5, so Rise by 3, then Run by -5… you are back at the origin. This tells you that the two slopes are equivalent, since they both keep you on the same line.
No matter which version you use, if you move from one point on the line using that slope you will end up at another point that DOES lie on the line… although perhaps in the other direction from the starting point. Debra, What you typed can be simplified, but not solved, as it does not include a variable or an equal sign with something on the other side. I am unsure whether you intended the expression to be a single fraction, as in Or interpreted as your calculator would They will have different results.
