For example, 1.414, 414, 414 has repeating patterns of decimals where 414 is repeating. Rational numbers can also be expressed in decimal form. They are between integers so they can't be a whole number nor the integer. Rational numbers can also have repeating decimals which you will see be written like this: 0.54444444 which simply means it repeats forever, sometimes you will see a line drawn over the decimal place which means it repeats forever, instead of having a ., the final number will have a line drawn above it. Whole numbers are easy to remember. Because no type of fraction is an integer. Another way to identify a rational number is to check whether it is a natural number, a whole number, an integer, or a fraction of integers. decimal equivalent goes on forever, with no repeating pattern: Other famous irrational This site is using cookies under cookie policy .
