Rational numbers are equivalent to ratios of two integers (the denominator being non-zero).
A ratio is a relationship between two set of values. For example, the ratio of the circumference of a circle to its diameter is pi, which is not a rational number.

Can a fraction be rational?
Yes it can. In fact, all real fractions are rational. Numbers are said to be rational that are ratios of the whole numbers. For example: 3/3 = 1 , therefore 1 is rational (and all other whole numbers) 2/3 = .666... , therefore .666... is rational because it is a ratio of 2 to 3. 123512/321235 also rational. There are some types of numbers, trancendental numbers, for example, for which no ratio exists. We call those numbers irrational. Famously, the number pi is the ratio between the diameter and circumfrence of a circle. There is no whole number ratio that can represent this relationship. Pi is both transendental and irrational.
Numbers that can be written as the ratio of two integers are called numbers?
Rational numbers.
What is the difference between decimal and rational number?
A number x is said to be rational if it can be expressed as the ratio p/q where p and q are integers, and q is not 0. For each rational number there is an equivalent decimal representation which is either a terminating decimal or one that has an infinitely recurring pattern. A decimal number which is infinite but without any recurring pattern is an irrational number.Thus rational numbers form a subset of decimal numbers.
What are rational numbers and what are irrational numbers?
They are both real numbers. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Can some integers be irrational numbers?
No, an integer n can be expressed as a ratio: n/1. It is, therefore, rational.
What is the relationship between a ratio and rational numbers?
A rational number is one which can be expressed as a ratio of two integers.
What is the difference between an irrational number and a rational numbers?
A rational number can be expressed as a ratio of two integers, p/q where q > 0. An irrational number cannot be expressed in such a way.
What is the difference between rational numbers and fractional numbers?
A fraction is a ratio of two numbers. Fractions are typically ratios of integers (where the denominator is not zero), which makes them "rational." The root word of rational is ratio. You could have pi/2, or sqr(2)/2, both of which are fractions that are NOT rational.
Are rational numbers counting numbers?
No. Rational numbers are those numbers that can be expressed as a ratio of two integers. 2.4, for example, is a rational number (it can be written as the ratio 12/5), but not a counting number.
What is the difference between real and rational numbers?
The rational numbers are a subset of the real numbers. You might recall that rational numbers are those that can be expressed as the ratio of two whole numbers (no matter how large they are). Irrational numbers, like pi, cannot. But both sets (the rational and irrational numbers) are subsets of the real numbers. In fact, when we look at all the numbers, we are looking at the complex number system. We break that down into the real and the imaginary numbers. And the real numbers have the rational and irrational numbers as subsets. It's just that simple.
The set of rational and irrational numbers?
ratio numbers
Is the ratio of two rational numbers always positive?
No; depends on the signs of the rational numbers.
What is a ratio of integers?
The ratio of integers to rational numbers is 0.
Are integers rational numbers yes or no?
Yes, integers are rational numbers. Rational numbers are defined as the set of numbers that can be expressed as the ratio of two integers, where the denominator is not zero. Since integers can be expressed as the ratio of itself divided by 1, they are considered rational numbers.
What is the difference between a ratio and a prportion?
a ratio is a fraction of two numbers a proportion is = fractions
Can all rational numbers be expressed as he ratio of two integers?
Yes, that is the definition of rational numbers.
What are numbers that can be expressed as a ratio of two integers?
rational numbers
