# Real Number System

### Practice Categorizing Real Numbers as Rational or Irrational.

ValueCategory
1.3456387... 1.3456387... is IRRATIONAL NUMBER because it's decimal value is non-repeating and non-terminating.
1/3 1/3 RATIONAL NUMBER because it is a fraction without a denominator of zero.
0 0 is a WHOLE NUMBER
-5 -5 is an INTEGER because it is the opposite of a whole number
500 500 is a NATURAL NUMBER because it is a counting number
29 29 is a NATURAL NUMBER because it is a counting number
8,760 8,760 is a NATURAL NUMBER because it is a counting number
1/6 1/6 is a RATIONAL NUMBER because it is a fraction without a denominator of zero.
PI Pi is an IRRATIONAL NUMBER because it's decimal value is non-repeating and non-terminating than cannot be expressed as a fraction.
THE SQUARE ROOT OF 2 THE SQUARE ROOT OF 2 is IRRATIONAL NUMBER because it's decimal value is non-repeating and non-terminating that cannot be expressed as a fraction.
1.33333.... 1.33333.... is a RATIONAL NUMBER because it is repeating decimal that can be expressed as a fraction without a denominator of zero.
1/8 1/8 is a RATIONAL NUMBER because it is fraction without a denominator of zero.
-1/2 -1/2 is a RATIONAL NUMBER because it is a fraction without a denominator of zero.
-1.5 -1.5 is a RATIONAL NUMBER because it is a terminating decimal that can be expressed as a fraction without a denominator of zero.
-1.3333.... -1.3333.... is a RATIONAL NUMBER because it is a repeating decimal that can be expressed as a fraction without a denominator or zero.
-0.37489289... -0.37489289... is an IRRATIONAL NUMBER because it is a non-repeating and non-terminating decimal that cannot be expressed as fraction.
THE SQUARE ROOT OF 1/9 THE SQUARE ROOT OF 1/9 is a RATIONAL NUMBER because it's value is 1/3 which is a fraction without a denominator of zero.
-3 -3 is an INTEGER because it is the opposite of a whole number
-21,000 -21,000 is an INTEGER because it is the opposite of a whole number
5/8 5/8 is a RATIONAL NUMBER because it is a fraction without a denominator of zero.
9/10 9/10 is a RATIONAL NUMBER because it is a fraction without a denominator of zero.
THE SQUARE ROOT OF 19 THE SQUARE ROOT OF 19 is an IRRATIONAL NUMBER because it's decimal value is non-terminating and non-repeating that cannot be expressed as fraction.
THE SQUARE ROOT OF 3 THE SQUARE ROOT OF 3 is an IRRATIONAL NUMBER because it's decimal value is non-terminating and non-repeating that cannot be expressed as fraction.
0.4 0.4 is a RATIONAL NUMBER because it is a terminating decimal that can be written as a fraction.
7.12121212... 7.12121212... is a RATIONAL NUMBER because it is a repeating decimal that can be written as a fraction.
THE SQUARE ROOT OF 9 THE SQUARE ROOT OF 9 is a RATIONAL NUMBER because it has a value of 3.
5/0 5/0 is an IRRATIONAL NUMBER because it is a fraction with a denominator of zero.
9/0 9/0 is an IRRATIONAL NUMBER because it is a fraction with a denominator of zero.
6/0 6/0 is an IRRATIONAL NUMBER because it is a fraction with a denominator of zero.
THE SQUARE ROOT OF 15 THE SQUARE ROOT OF 15 is an IRRATIONAL NUMBER because it is not a perfect square. The decimal value does not repeat and is non-terminating.
THE SQUARE ROOT OF 122 THE SQUARE ROOT OF 122 is an IRRATIONAL NUMBER because it is not a perfect square. The decimal value does not repeat and is non-terminating.
THE SQUARE ROOT OF 5 THE SQUARE ROOT OF 5 is an IRRATIONAL NUMBER because it is not a perfect square. The decimal value does not repeat and is non-terminating.
THE SQUARE ROOT OF 20 THE SQUARE ROOT OF 20 is an IRRATIONAL NUMBER because it is not a perfect square. The decimal value does not repeat and is non-terminating.
22/7 22/7 is a RATIONAL NUMBER because it is a fraction without a denominator of zero. (Beware...this is an estimate for PI and not really equal to Pi.)
3.14 3.14 is a RATIONAL NUMBER because it is a fraction without a denominator of zero. (Beware...this is an estimate for PI and not really equal to Pi.)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
