Parts of a fraction 12

  • denominator The number under the bar: the count of equal parts in all. In 5/8 the denominator is 8.
  • eighth A single piece of a thing cut into eight equal pieces. An eighth of 16 is 2.
  • fraction A number for a part, such as three fourths. 3/4 names three of four equal parts.
  • fraction bar The line that separates the top number from the bottom. It can be read as "over" or "divided by".
  • half Either piece of a thing cut into two equal pieces. Half of 18 is 9.
  • numerator The number over the bar: the count of parts taken. In 5/8 the numerator is 5.
  • quarter Any of the four equal parts of a whole. A quarter of 8 is 2. Another name is a fourth.
  • ratio How large one amount is next to another, as in 3 to 4. 3 red beads to 4 blue beads is the ratio 3 to 4.
  • slash The slanted stroke in a fraction typed on one line. 3/4 is typed with a slash.
  • third A single piece of a thing cut into three equal pieces. A third of 12 is 4.
  • unit fraction A fraction with 1 as its top number. 1/5 is a unit fraction.
  • whole The complete thing, equal to 1. A pizza cut into six slices is still one whole.

Kinds of fraction 12

  • common fraction A fraction shown as two integers, not as a decimal. 3/8 is a common fraction; 0.375 is not.
  • complex fraction A fraction with a fraction in its top or its bottom. 1/2 over 1/3 is a complex fraction; it equals 3/2.
  • compound fraction A fraction of a fraction. 3/4 of 5/7 is a compound fraction; it equals 15/28.
  • decimal fraction A fraction with 10, 100, 1000 and so on underneath. 37/100, written 0.37, is a decimal fraction.
  • Egyptian fraction A sum of different unit fractions. 1/2 + 1/3 is an Egyptian fraction for 5/6.
  • equivalent fractions Two or more fractions with one value, written differently. 2/3 and 4/6 are equivalent fractions.
  • improper fraction A fraction of 1 or more: its top is not the smaller number. 7/4 and 4/4 are improper fractions.
  • mixed number An integer joined to a fraction, as in two and a half. 4 2/3 is a mixed number equal to 14/3.
  • percent An amount out of 100, written with the sign %. 25 percent is 25/100, or 1/4.
  • proper fraction A fraction less than 1: its top number is the smaller. 2/3 is a proper fraction.
  • rational number A number equal to one integer divided by another. 0.2 is a rational number because it equals 1/5.
  • repeating decimal A decimal whose digits repeat in a pattern forever. 1/3 = 0.333...

Working with fractions 12

  • cancel To strike out a factor found in both top and bottom. In 6/8, cancel the factor 2 to get 3/4.
  • common denominator A bottom number that two or more fractions share. 1/2 and 1/3 can both be written with the common denominator 6.
  • compare To find which of two fractions is larger. 5/6 is greater than 3/4, because 10/12 is greater than 9/12.
  • convert To rewrite a number in another form. 1/4 converts to 0.25.
  • cross-multiplication Multiplying each top by the other fraction's bottom. For 2/3 and 4/6: 2 × 6 = 12 and 3 × 4 = 12, so they are equal.
  • greatest common divisor The biggest number by which every number in a set divides. For 12 and 18 it is 6.
  • invert To swap the numerator and the denominator. Inverting 2/5 gives 5/2.
  • least common denominator The smallest bottom number that fractions can share. For 1/4 and 1/6 it is 12.
  • least common multiple The smallest number that is a multiple of each given number. For 4 and 6 it is 12.
  • lowest terms The form of a fraction with no factor common to both parts. 3/8 is in lowest terms; 3/9 is not.
  • reciprocal What 1 becomes when it is divided by a number. The reciprocal of 2/3 is 3/2.
  • simplify To bring a fraction down to its smallest numbers. 6/8 simplifies to 3/4.

How it works

This fraction vocabulary worksheet prints twelve terms down the left and their meanings, mixed up, down the right. Three sets cover the parts of a fraction, the kinds of fraction, and working with fractions.

Read the full guide

Three sets

Set opens on Parts of a fraction: numerator, denominator, fraction bar, whole, half, third, quarter and unit fraction. Kinds of fraction has proper, improper, equivalent and mixed number. Working with fractions has simplify, common denominator, reciprocal and cancel.

Numbers after every meaning

Under the tool each meaning is followed by an example: 6/8 simplifies to 3/4; the reciprocal of 2/3 is 3/2. Type term = meaning lines in the box to print your textbook's wording in place of ours.

Questions and answers

What are the parts of a fraction called?

The top number is the numerator and the bottom number is the denominator. The line between them is the fraction bar. In 5/8 the numerator is 5 and the denominator is 8.

What is the difference between a proper and an improper fraction?

A proper fraction is less than 1, so its top number is the smaller, as in 2/3. An improper fraction is 1 or more, as in 7/4 or 4/4, and can be rewritten as a mixed number.

What is a unit fraction?

A fraction with 1 as its top number, such as 1/5. An Egyptian fraction, in the second set, is a sum of different unit fractions, such as 1/2 + 1/3.

Does it print an answer key?

Yes, as the last page: the sheet again, with each term joined to its meaning by a line. The check box that removes it is under More options.
