What is the numerator?
The numerator is the upper part of the fraction, a mathematical expression that expresses part of the whole. For example, 7/19 is a fraction, while the numerator of this particular fraction is "7." Similarly, 8/3 is also a fraction. The lower part of the fraction is known as the denominator, while some people use the term "nominetor" to talk about the numen. The numerator describes the number of parts of the entire fraction.
The fraction can be written with a vertical or horizontal rod depending on personal taste and convention. In complex equations, fractions are often written with horizontal stripes, so it is easy to see. Usually, fractions are simplified to the so -called non -removable fractions, so it would be unusual to see a fraction as a 3/9 that would be represented instead of 1/3. It is also important to simplify fractions because it allows people to see the relationship between different fractions and make equations with fractions. For example, the connection between 8/12 and 3/9 is much easier to see when these fractions are simplified to 2/3 and 1/3.
When people simplify fractions to compare them, they begin to search for the lowest common denominator, the smallest time of denominators involved in comparing fractions. In the above example, the lowest common denominator is 36, because both 12 and 9 can be multiplied to form 36, 12 three times and nine four times. This example is a relatively easy calculation; Other fractions can make it difficult to find the lowest common denominators.
by multiplying the numerator and the denominator in the first faction by three and in the second fraction of four to achieve the lowest common denominator while maintaining the right proportions in the fraction, fractions can be expressed as 24/36 and 12/36. These fragments are very clumsy, so you include the next step, you include the largest common divisor, the largest number that can be used to divide the numeors and denominators, while maintaining them as the whole number.
The largest common divisor in our example becomes 12. When they are allI numerators and denominators divided 12, the resulting fractions are 2/3 and 1/3. It is important to maintain the relationship between the numerator and the denominator to ensure that the fraction remains the same, which means that any operation on the numerator must be performed on the denominator and vice versa. In our example, if someone could not be multiplied by the numerator 8/12 when multiplied by the denominator, the resulting fraction would be 8/36, which is a very different fraction from 24/36.
