Rational numbers are roots, decimals, fractions, and whole numbers. Bascially anything that can become a decimal. Irrational numbers are like pi. I'm pretty sure to be irrational, they have to repeat.

Anyway, ordering them and comparing them means looking at them and seeing which is smallest and largest. Then you order them (smallest to largest or whatever it says).

In the real world you can use the order of rational numbers. This is used a lot in math.

This means:Draw a number line with some numbers labelled on it.Place dots on the number line where the rational numbers to be compared lie.State how the numbers compare in size with one another.There are various ways of doing this; here are two:1/2 is less than 5/41/2 < 5/4

You do not, but it is easier.

Convert them all to their decimal equivalents (by dividing each numerator by its denominator), then you can easily see which numbers are greater than others.

This answer is irrelevant because you did not explain yourself, the correct answer is,"Its important so you can separate whole numbers for parts of whole numbers."

The comparing and ordering of numbers is referred to as factorization. Numbers are factored into certain multiples such that the resolution of the entity into the factors when multiplied together will give the original entity.

Rational numbers are (basically) fractions. You can compare any two fractions by converting them to fractions with a common denominator, and then comparing their numerators.You can also convert them to their decimal equivalent (just divide numerator by denominator); that also makes them fairly easy to compare.

They are similar because when you compare decimals you say the larger one has more value so the decimal is larger like in comparing whole numbers the number that has more value is larger. So they are very similar.

Convert all the rational numbers to order into equivalent fractions with the same denominator; then they can be ordered by putting the numerators in order from least to greatest. ------------ You can also convert all the numbers to decimals ... this is actually a special case of "equivalent fractions".

There are no consecutive rational numbers. Between any two rational numbers there are an infinity of rational numbers.

If there are no numbers after the 9 it is rational

No. Rational numbers are numbers that can be written as a fraction. All rational numbers are real.
