### Carnegie Rational Numbers - Fractions

fraction Represents a part of a whole object, set, or unit. Written using two whole numbers separated by a bar.
numerator The number above the fraction bar. It indicates how many parts in the whole are counted.
denominator The number below the fraction bar. It indicates how many parts make up the whole.
unit fraction This has a numerator of 1 and a denominator that is a positive integer greater than 1.
equivalent fractions These represent the same whole
benchmark fractions Common ones that are used to estimate how much others are. An example is 1/2.
inequality Any mathematical sentence that shows a comparison.
simplest form A way of writing a fraction so that the numerator and the denominator have no common factors other than 1.
Multiplicative Identity Property This states that a X 1 = a, where a is a nonzero number.
common denominator a whole number that is a common multiple of the denominators of two or more fractions.
least common denominator (LCD) The least common multiple of the denominators of two or more fractions.
mixed number This has a whole number part and a fraction part.
improper fraction A fraction in which the numerator is greater than or equal to the denominator.
reciprocal This is also known as the multiplicative inverse of the number.
Multiplicative Inverse Property This states that a/b X b/a = 1, where a and b are nonzero numbers.
multiplicative inverse This means that for the fraction a/b this would be b/a, where a and b are nonzero numbers. The product of these two fractions is 1.

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.
