Numbers are either irrational (like the square root of 2 or pi) or rational (can be stated as a fraction using whole numbers). Irrational numbers are never rational.

Yes, as long as the two nonzero numbers are themselves rational. (Since a rational number is any number that can be expressed as the quotient of two rational numbers, or any number that can be written as a fraction using only rational numbers.) If one of the nonzero numbers is not rational, the quotient will most likely be irrational.

-- Any number that you can completely write down using digits, and a decimal point or fraction bar if needed, is rational. -- A rational number is defined as one that can be written as a fraction using whole numbers. -19 can be written as the fraction -19/1 .

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.

-- Any number that you can write as a whole number, a fraction, or a mixed number, using digits, is rational. -- Any number that you can completely write down on paper, using digits, is rational.

-- It's rational if there's any way to write it as a fraction that has whole numbers on the top and bottom. -- It's rational if you can write it down on paper completely, using digits.

The LCM is used to convert unlike rational fraction to like fractions so that they can be added or subtracted. Any common multiple will do so the LCM is not that important. However, using the LCM will ensure that the numbers that you have to deal with are as small as they can be.

It means that the answer can be written as a fraction using whole numbers (integers) i.e. 3/4 or 1/8 or 5 (which is identical to 5/1 and hence rational)

You can easily convert a decimal to fraction. For that you have to divide by 10 to the power numbers that are after the decimal.

For a number to be rational you need to be able to write it as a fraction. To answer your question, it must repeat as a decimal or else terminate which can be thought of as repeating zeroes. Further, every repeating decimal can be written as a fraction and you can find the fraction by using the formula for the sum of an infinite geometric series.

Any number that you can completely write down using digits is rational.Let's try to write 2.51 completely with digits:2.51That's it! We're pretty sure that 2.51 is rational. The official math definition of a rational number is: A number that can be writtenas a fraction made of whole numbers. Let's try and write 2.51 as a fractionmade of whole numbers:251/100We did it again! 2.51 is definitely rational.

It means that either the numbers involved in the word problem are all rational or that any irrational numbers are being approximated by rational numbers.

A rational number is one that can be represented as an integer or a fraction with an integer over an integer. An irrational number cannot be represented using integers. Examples of rational numbers: 2, 100, 1/2, 3/7, 22/7 Examples of irrational numbers: π, e, √2

Multiply both numbers by five- to get the fraction 85/100... which is 85%

Yes. That in itself is the definition of a rational number. A rational number is one that can be expressed through a ratio of two integers using an integer numerator and denominator (so in simple terms, a fraction). A rational number is able to be written as a terminating decimal.

If I understand this right, you want to know how to convert a fraction into a decimal with the aid of a calculator. This is usually done by pressing the fraction button on your calculator which changes it from a fraction to a decimal and vice versa.

Z=Integers; Rational numbers={a/b| a,b∈Z, b ≠ 0}.

It is the ratio of the two numbers.

Rational numbers are numbers that can be expressed as a fraction of two integers. For example, 2/3, 8/27, and 4/1 are all rational numbers. In decimal form, those three numbers would be written as .66666666666... (I'm using the "..." to represent the fact that those 6's after the decimal point continue on forever), .296296296296296..., and 4, respectively. Notice how those three numbers, when written in decimal form, either repeat some pattern after their decimal point, or end. This is, in fact, the case for every rational number; they either terminate, or they have an infinite amount of some repeating number or group of numbers after their decimal point.Irrational numbers differ from rational numbers in that none of the above apply; i.e., they can't be expressed as a fraction of two integers, they don't repeat indefinitely, and they don't end. A couple of famous examples of irrational numbers are pi and the square root of two.

That's a 'rational' number.

-- Any number that you can completely write down using digits is a rational number. -- A rational number is one that can be written as the ratio of two whole numbers. 1.9 is the ratio of 19 and 10.

Using toString() method

No, it's rational. Any number that you can completely write down, using digits and a decimal point or a fraction bar, is rational.
