numerator
Meaning: The number above the line in a fraction, representing how many parts of the whole are being considered.
The numerator tells you how many equal parts are taken from the total indicated by the denominator. For instance, in 3/4, the numerator is 3. Understanding the relationship between numerator and denominator is fundamental to working with fractions, ratios, and proportions. The term is also used in statistics and finance when discussing rates and ratios.
Examples
- In the fraction three quarters, the numerator is three. 在四分之三这个分数中,分子是三。En la fracción tres cuartos, el numerador es tres.4分の3という分数では、分子は3である。4분의 3이라는 분수에서 분자는 3이다.
- To add fractions with the same denominator, simply add the numerators. 当分母相同时,只需将分子相加即可完成分数加法。Para sumar fracciones con el mismo denominador, basta con sumar los numeradores.分母が同じ分数を足すには、分子を足すだけでよい。분모가 같은 분수를 더할 때는 분자끼리 더하기만 하면 된다.
- Increasing the numerator whilst keeping the denominator constant makes the fraction larger. 在分母不变的情况下增大分子,分数会变大。Si se aumenta el numerador manteniendo constante el denominador, la fracción se hace mayor.分母を一定に保ったまま分子を大きくすると、分数の値は大きくなる。분모를 일정하게 유지한 채 분자를 크게 하면 분수의 값이 커진다.
