numerator

**Numerator** (с английского — «числитель») — это число или выражение, которое находится в верхней части дроби и показывает, сколько частей целого берётся.

Вот несколько примеров использования слова «numerator» в предложениях:

1. In a fraction, the numerator represents the number of parts you are taking. For example, in the fraction 3/4, **the numerator is 3**, which means you are taking three parts of the whole.
2. To find the equivalent fraction, you need to multiply both the numerator and the denominator by the same number. For instance, if you have the fraction 2/5 and you want to find its equivalent with a numerator of 6, you would multiply both by 6 and get 12/30.
3. When comparing fractions, the numerators are important to determine which fraction has more parts. For example, if you compare the fractions 5/8 and 3/4, you see that **the numerator of the first fraction is greater**, so it represents more parts than the second fraction.
4. To add or subtract fractions, you need to have the same denominator. If the denominators are different, you need to find a common denominator. For instance, to add the fractions 1/3 and 2/5, you first need to find a common denominator, which is 15. Then you multiply the numerator and denominator of each fraction by the required number to get equivalent fractions with a common denominator. The resulting fractions are 5/15 and 12/15, and their numerators can be added: 5 + 12 = 17.
5. When working with percentages, the numerator is the number of parts out of 100. For example, 75% is read as «seventy-five percent» and means that there are 75 parts out of 100.
