Can an rational number be a decimal
WebRational numbers can easily be represented in the decimal forms by dividing the numerator ‘p’ by the denominator ‘q’ (given that rational numbers are in the form of p/q). A rational number can be expressed as a terminating or nonterminating, recurring decimal. example: 7/2= 3.5, 4/8 = 0.5, 10 = 10.0 WebJan 25, 2024 · Their number of decimal places is finite. These decimal numbers are called exact decimal numbers. We can represent these decimal numbers in \ (\frac {p} {q}\) form where \ (q \ne 0\) or we can represent decimal numbers as rational numbers. For example, \ (2.665\) are the terminating decimal number.

WebThese are two different ways of representing the same number. A rational number is a number that can be represented a/b where a and b are integers and b is not equal to 0. A rational number can also be represented in decimal form and the resulting decimal is a repeating decimal. (I see the decimal 0.25 as repeating since it can be written 0. ... WebFor example: 5 2, 3 7, 4 1, 1 3 and 0 1 are rational numbers, but for 5 0 or 1 0 the denominator is equal to zero and the value of 5 0 or 1 0 is not defined, so they are not rational numbers. A rational number in fractional form can also be expressed in decimal form. The decimal form of rational number is either,
WebTo decide if an integer is a rational number, we try to write it as a ratio of two integers. An easy way to do this is to write it as a fraction with denominator one. 3= 3 1, −8= −8 1, 0= 0 1 3 = 3 1, − 8 = − 8 1, 0 = 0 1. Since any integer can be written as the ratio of two integers, all integers are rational numbers. Web9. Here's a proof in the opposite direction: Every positive rational number has either a terminating or repeating decimal expansion, and the positive rational numbers p q (in lowest terms) which have a finite expansion are precisely where q has the form 2a5b with a, b non-negative integers. If q has the form 2a5b, then 10 max ( a, b) p q is an ...
