Fractions
Parts of a whole — halves, thirds, quarters and beyond.
A fraction is a part of a whole. Half (½) means one of two equal parts. A quarter (¼) is one of four equal parts.
A fraction a/b means a parts when a whole is split into b equal parts. The bottom number (denominator) says how many equal parts; the top (numerator) says how many we have.
A rational number a/b represents the quotient a÷b and a partition of unity into b equal parts, of which a are taken. Equivalent fractions (a/b = ka/kb) arise from scaling numerator and denominator together.
