We know that a real number is rational if and only if, when expressed as a decimal, it has a finite or recurring expansion.
. . (put a point exactly over 8 and 2).
For example, 5/4 = 1.25, 2/3 = 0.6, 20/7 = 2.857142857 or 20/7 = 2.857142
It is still a rational number.
0.7 IS is a rational number. It is in the form of a terminating decimal.
12.52 is rational, as is any number that you can write out completely in decimal form.
I think it's a repeating decimal.
The number 3.33333 is a rational number, specifically a repeating decimal. It can be expressed as 10/3 in fraction form, which means it can be written as a ratio of two integers. Rational numbers can be written as terminating decimals or repeating decimals, like in this case.
Rational Numbers are any number that can be written in fraction form .This includes integers, terminating decimals, and repeating decimals as well as fractions. A decimal number can be written in rational numbers depending on the place value of the decimal point.
It is still a rational number.
An irrational number cannot be written as a fraction or to an exact decimal such as the symbol for pi or the square root of two. A rational number can be written in the form of a fraction or a decimal to an exact value.
Repeating decimal
It is a rational number, in decimal form. In the form of a ratio, it is 11/100.
It is a negative rational number in decimal form. It is also a real number.
Any terminating or repeating decimal number can be converted easily into the form of p/q: a ratio of two integers. If it can be written in that form then it is rational.
A rational number is any number that can be written in the form of one integer over another integer; all rational numbers have a decimal form that either terminates or repeats one, or more, digits forever. 4.680 is a terminating decimal, therefore it is a rational number. 4.680 = 4680/1000 = 468/100 = 117/25 -------------------------- The decimal form of a rational number will repeat forever if the prime factorization of the denominator contains any prime other than 2 or 5.
Yes, for example 3/2 can be written as 1.5. All rational numbers have either a decimal expression of finite length or a repetitive pattern, unlike an irrational number, which goes on for ever when written in decimal form, never repeating.
0.7 IS is a rational number. It is in the form of a terminating decimal.
In non-decimal form, it is either a whole number of written as a fraction (a ratio) of two whole numbers. In decimal form, it is either terminating or (after a finite number of digits) recurring.
Any number that can be written in fraction form is a rational number. This includes integers , terminating decimals , and repeating decimals as well as fractions. An integer can be written as a fraction simply by giving it a denominator of one so any integer in a rational number.
