What is the numerator?
In a fraction, the numerator is the number above the line: it indicates the quantity of parts of the unit, or of the whole, to be counted. Numerator ---------------- fraction bar Denominator For example: In ¼, the numerator is 1; In ¾, the denominator is 4. The numerator can be indicated by a cardinal number.
What does numerator vote and denominator vote mean?
- the denominator is the number below the fraction line and indicates how many equal parts the whole must be divided, ie the quantity that is considered as a unit; - the numerator is the number above the fraction line and specifies how many parts of the whole are to be counted.
What is the denominator?
In a fraction, the denominator is the number below the fraction line and indicates into how many parts (fractions) the whole unit, or more generally the quantity that is taken as a unit, must be divided.
What are the numerators?
numerator In mathematics, the number of fractional units of a fraction: for example, 5 in the fraction 5/10, which represents the number obtained by taking 5 times the fractional unit 1/10. fraction Each of the parts into which a whole is divided; or detached part of a whole.
How to divide the numerator and denominator?
Another way to perform the division between two fractions is to multiply the numerator of the first fraction by the denominator of the second fraction and put the product obtained as the numerator of another fraction; then multiply the denominator of the first fraction by the numerator of the ...

How is the quotient between numerator and denominator calculated?
The product of two or more fractions is equal to a fraction which has the product of the numerators as its numerator and the product of the denominators as its denominator. The quotient of two fractions is obtained by multiplying the first fraction by the inverse of the second.
How to calculate the quotient between numerator and denominator?
If we multiply the divisor and the dividend by the same number, the value of the quotient does not change. Let's take the example of the numbers A, B and C. We multiply A by the quotient of B and C. You will find a result where the numerator is the product of A x B and the denominator is equal to C.
How to find the numerator?
Above the fraction line you write the number of parts I take into consideration. In our example they were the parts I ate and they were 3. The number above the fraction line is called the numerator.
How to calculate the numerator?
To multiply fractions we need to multiply the numerators of the fractions to get the new numerator, then multiply the denominators of the fractions to get the new denominator. The resulting fraction should be simplified if possible.
What is a fraction called if the numerator is a multiple of the denominator?
Proper fractions, improper fractions and apparent fractions are types of fractions where the numerator is less than the denominator, the numerator is greater than the denominator, the numerator is a multiple of the denominator, respectively. In particular, the apparent fractions can be expressed as whole numbers.
How do you find the common denominator?
1) We take the denominators and break them down into prime factors. 2) From these decompositions the common and uncommon factors are taken only once and with the maximum exponent. 3) The product of these factors is precisely our lowest common denominator, that is, the lowest common multiple of denominators.
Why does the denominator have to be non-zero?
Clearly this is a meaningless fraction, since any number multiplied by zero gives zero. So this fraction is IMPOSSIBLE. Therefore every FRACTION that has ZERO for the DENOMINATOR (and a number DIFFERENT from ZERO to the NUMERATOR) is meaningless and is called IMPOSSIBLE.
How to explain the fractions in a simple way?
A fraction consists of three elements: a center line, a number above and a number below. The number above the line is the numerator: it indicates how many parts of the whole we are considering. The number below the line is the denominator: it indicates how many equal parts the whole is divided into.
What grade is 60 out of 100?
The score is expressed in hundredths and the minimum grade is 60/100, which corresponds to passing. They can range from a minimum of 22 to a maximum of 40 points.
What does report card grade basis mean?
Basic level Grade (5/6) Competence is acquired in an essential way: the pupil performs the tasks in a guided form and demonstrates a basic awareness of knowledge Intermediate level Grade (7/8) Basic level Grade (5/6) Competence is acquired in an essential way: the pupil performs the tasks in a guided form and ...
What is meant by base grade?
Now that you know your weighted average, you can calculate the base grade from which you will start. To get it, you will simply have to multiply the value of your weighted average by 11 and then divide it by 3. 88,5 is therefore your basic grade, to which you will only have to add the points of the thesis.
How to bring a denominator to the numerator?
The rationalization technique is a method that allows you to simplify the fractions in which radicals appear in the denominator, and thanks to which you can rewrite a ratio of fractions by eliminating the radicals in the denominator, in order to transfer them to the numerator.
How is an addition between fractions solved?
To add (or subtract) two fractions that have the same denominator, we write a fraction that has: as denominator the same denominator of the given fractions; • as numerator the sum (or the difference) of the numerators. The result is reduced to a minimum, if it is possible.
How do you reduce it to a minimum?
Reducing a fraction to its lowest terms means transforming it into an equivalent fraction having the smallest terms (numerator and denominator). This transformation occurs by simplifying all the common divisors between the numerator and denominator.
What happens if the numerator is zero?
a fraction represents the exact quotient of the division between numerator and denominator. Non-zero numerator and denominator = 0, the fraction is meaningless. Numerator = 0 denominator = 0, the fraction is indeterminate, i.e. it can have any value.
How do you recognize a fraction reduced to a minimum?
A fraction is said to be reduced to its lowest terms (or irreducible) when the numerator and denominator do not have common divisors greater than 1, that is, they are prime to each other.
When is the numerator equal?
Two fractions are equivalent if the product of the numerator of the first by the denominator of the second is equal to the product of the denominator of the first by the numerator of the second. In this lesson you will see how to recognize fractional units, i.e. each of the equal parts into which you have divided the whole.
How to calculate the quotient between two numbers?
7: 4 = 7/4; 3: 5 = 3/5; 19: 13 = 19/13. the QUOTIENT between the two numbers can be written indifferently as: a: b or a / b. This QUOTIENT takes the name of RATIO between a and b.
How do you calculate the quotient of a number?
Note that quotient is by definition an integer: it is what is obtained when dividing by hand: eleven divided by three equals three (quotient) with the remainder of two (remainder). The quotient is 15 while the remainder is 3. Note that the quotient is always an integer (as is the remainder).
How is the intelligence quotient calculated?
Calculation of the IQ. To calculate the IQ you must first establish your mental age through special tests (also called scales), such as the Wechsler-Bellevue. The result obtained must be divided by the age and multiplied by 100.
