similarities and differences between ordinary fractions and rational expressions.
All fractions with integer numerator and non-zero integer denominator are rational, and conversely.
Yes, mixed fractions are rational
Rational expressions are fractions and are therefore undefined if the denominator is zero; the domain of a rational function is all real numbers except those that make the denominator of the related rational expression equal to 0. If a denominator contains variables, set it equal to zero and solve.
There are infinitely many rational numbers between any two consecutive rational numbers. This is because rational numbers can be expressed as fractions, and between any two fractions, an infinite number of other fractions can be found by taking the average of the two given fractions. Therefore, the set of rational numbers is dense, meaning there is no smallest gap between any two rational numbers.
Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.
All fractions with integer numerator and non-zero integer denominator are rational, and conversely.
For example: 1/2+1/4+1/8 are dissimilar fractions but also a rational expression that can be simplified to 7/8
They both can be expressed as fractions whereas irrational numbers can't be expressed as fractions.
Fractions are not integers. They may or may not be rational numbers.
Another rational expression.
Yes.
Yes, mixed fractions are rational
If you divide a rational expression by another rational expression, you will again get a rational expression.
All fractions are rational numbers.
Fractions are rational by definition.
Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
No, because all fractions are rational numbers
