Definition
Meaning
The number above the line in a fraction, representing the number of parts being considered.
A person or thing that counts or enumerates. In statistics, the top number in a ratio or calculation.
Linguistics
Semantic Notes
The term is primarily mathematical but carries a secondary literal meaning ("one who counts"), which is rare and chiefly historical or in specialized contexts like data processing.

Examples
By CEFR Level
- In the fraction 3/4, the numerator is three.
- To compare fractions, sometimes you need to find a common numerator first.
- The numerator of the equation had to be factored before the division could be completed.
- Statistical significance is determined by examining the ratio, where a small p-value often results from a large test statistic in the numerator.
Learning
Memory Aids
Mnemonic
Think of NUMerator as the "number-up-top," reminding you of its position in a fraction. It NUMbers the parts you have.
Conceptual Metaphor
A PART-WHOLE schema (the numerator is the counted part of the whole represented by the denominator). A CONTAINER metaphor (the fraction bar is a container; the numerator is the content).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'числитель' (correct translation). Do not confuse with 'нотариус' (notary). The word sounds similar to 'number' in English, which can help recall.
Common Mistakes
- Pronouncing it as /ˈnʌm.ə.reɪ.tə(r)/ (like 'number').
- Using 'nominator' instead (which is incorrect; 'nominator' is not a standard maths term).
- Thinking it refers to the bottom number of a fraction.

Frequently Asked Questions
Yes, but it's rare. Its literal meaning is 'a person or device that counts,' but this is mostly historical or found in very technical contexts like computing.
The numerator (top number) and denominator (bottom number) together define a fraction. The denominator shows how many equal parts the whole is divided into, and the numerator shows how many of those parts are taken.
No. In a proper fraction it is smaller, but in an improper fraction (like 7/4) the numerator is larger than or equal to the denominator.
In British English: /ˈnjuː.mə.reɪ.tə(r)/. In American English: /ˈnuː.mə.reɪ.t̬ɚ/. The main difference is the first vowel ('nyoo' vs 'noo').
