Rappel : on appelle nombre entier un nombre comme 0 – 1 – 2 - 3
Si on divise ou multiplie le numérateur et le dénominateur d'une fraction par le même nombre on obtient une fraction égale.

égales. Chaque carreau représente donc un quart. 3 est le numérateur : Il indique que l'on a pris 3 parts. On a pris 3 quarts. : 10
avec un numérateur égal à 15. Solutions : 5. 4. = 5×3. 4×3. =.
3 : 4 « En posant éventuellement la division ». Ainsi : N. 3. = 3 : 4 = 075 Pour chacune des fractions suivantes
Une fraction est un nombre qui représente des parts égales de l'unité (par exemple des parts égales de gâteau). Dans une fraction il y a 2 nombres :.
FRACTION. Trois cinquièmes. On partage l'unité en cinq parts égales et on prend Par exemple : 34 + 12
4 Complète cette suite de fractions. Entoure la fraction égale à 2. 7. 2. 3. 4.
le dénominateur de la fraction égale à soit égal au numérateur de la fraction égale à Calcule les quotients : 3 4 ; 3 4 et 3 4 .
4× 3 = 9 12 Multiplying by 10 gives 3×10 4×10 = 30 40 and all of these fractions are exactly the same as 3 4 When dealing with fractions we often use some special mathematical language Instead of using the words ‘top number’ and ‘bottom number’ we use the words numeratorand denominator So in 3 4 3 is the numerator and 4 is the

4) Pour simplifier une fraction : On repère dans quelle table de multiplication se trouvent le numérateur et le dénominateur On écrit cette multiplication et on barre le même nombre en haut et en bas On essaie 2 3 et 5 pour commencer Exemples : 8 10 = 2 x 4 2 x 5 = l 4 5 9 12 = 3 x 3 3 x 4 = l 4 3 Remarques :
Unlike adding and subtracting integers such as 2 and 8, fractions require a common denominator to undergo these operations. One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the product of the denominators of each fraction. Multiplying all of the denominators ensures...
Fraction subtraction is essentially the same as fraction addition. A common denominator is required for the operation to occur. Refer to the addition section as well as the equations below for clarification.
Multiplying fractions is fairly straightforward. Unlike adding and subtracting, it is not necessary to compute a common denominator in order to multiply fractions. Simply, the numerators and denominators of each fraction are multiplied, and the result forms a new numerator and denominator. If possible, the solution should be simplified. Refer to th...
The process for dividing fractions is similar to that for multiplying fractions. In order to divide fractions, the fraction in the numerator is multiplied by the reciprocal of the fraction in the denominator. The reciprocal of a number ais simply
It is often easier to work with simplified fractions. As such, fraction solutions are commonly expressed in their simplified forms.
Converting from decimals to fractions is straightforward. It does, however, require the understanding that each decimal place to the right of the decimal point represents a power of 10; the first decimal place being 101, the second 102, the third 103, and so on. Simply determine what power of 10 the decimal extends to, use that power of 10 as the d...
Fraction Calculator 1 Mixed Numbers Calculator 2 Simplify Fractions Calculator 3 Decimal to Fraction Calculator 4 Fraction to Decimal Calculator 5 Big Number Fraction Calculator. Use this calculator if the numerators or denominators are very big integers. In mathematics, a fraction is a number that represents a part of a whole.
For example, in the fraction 3 5 , the numerator is 3, and the denominator is 5. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator.
