A whole partitioned into four equal parts has four fourths, with each part representing one fourth, or , of the whole; therefore, four copies of make whole. This relationship connects fraction notation, equal partitions of shapes or lengths, and points on a number line, while distinguishing fourths from unequal parts or parts of different-sized wholes.
On this page:
A fourth is one of four equal parts of a whole. Each part is written as .
Example: A rectangle is split into 4 equal parts, and all 4 parts are shaded.
So, the entire rectangle is four fourths, which equals one whole. The parts must be equal in size for them to be fourths.
