Ordering
What is Ordering?
Arranging quantities by size, from smallest to largest or the reverse, after converting them all into one comparable form or locating them on a number line. On a number line the smaller of two numbers is always the one further to the left, which is what makes negative eight smaller than negative three.
This definition is part of the Number chapter in Cambridge O Level Mathematics (Syllabus D).
Ordering in context
Fractions, decimals and percentages are one number wearing three coats. Choose the coat that suits the job: fractions for exact work and cancelling, decimals for ordering and calculator entry, percentages for comparison and change. The conversions themselves are only three operations — divide, use place value, and multiply or divide by 100 — and every one of them is reversible.
