0All 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.

Another rational expression.

Fractions are not integers. They may or may not be rational numbers.

If you divide a rational expression by another rational expression, you will again get a rational expression.

Yes, mixed fractions are rational

Rational numbers are, in essence, numbers that can be written as fractions using two integers (one for the numerator, the other for the denominator). Not all fractions are rational numbers, though; it is possible to write a pattern describing a fraction that goes on forever to represent irrational numbers like pi.

All fractions are rational numbers.

Short answer - yes, fractions with whole numbers are rational. All whole numbers are rational. All fractions are rational. Rational numbers can be added to always make another rational number.

No. All integers are also rational and they are not fractions.

Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.

Fractions are rational by definition.

They are rational fractions.

This number is rational - all fractions, including decimal fractions and mixed numbers are rational.

No, because all fractions are rational numbers

All fractions are rational numbers because irrational numbers can't be expressed as fractions

The expression written in the question is the rational expression.

Yes it is.Rational numbers can be written are fractions. three is a rational number.

All fractions with whole numbers on top and bottom are rational numbers,and many fractions with decimals on top or bottom, or both, are also rationalnumbers.

Numbers that can be expressed as fractions are rational

The difference is that rational numbers can be expressed as fractions whereas irrational numbers can not be expressed as fractions.

All rational fractions.

All numbers that can be expressed as fractions are rational
