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).

### How can you interpret thr ordering of rational numbers in real world situations?

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

### What is comparing ordering rational number using a number line?

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

### What do you need to line up decimal points before comparing and ordering numbers with decimals?

You do not, but it is easier.

### Order rational numbers?

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.

### How are comparing and ordering whole numbers and decimals similar?

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.

### How comparing and ordering fractions?

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.

### How can you solve problems by ordering rational numbers from least to greatest?

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".

### How many rational numbers are there between two consecutive rational numbers?

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

### Is 3.9 rational or irrational?

If there are no numbers after the 9 it is rational

### Are some rational numbers are not real numbers?

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