Fractions — basic ideas

1 Introduction What are fractions? Fractions are ways of writing parts of whole numbers For example if we take a pizza and divide it up equally between 4 people each person will have 1 or written in 4 words one quarter of the pizza pizza 1⁄4 pizza If one person were to take 2 quarters of the pizza they would have half the pizza So

How do you use fractions in math?
In math, we use fractions to depict these values. fraction consists of two numbers separated by a bar in between them. The bottom number, called the denominator, is the total number of equally divided portions in one whole. The top number, called the numerator, is how many portions you have.
What is a proper fraction?
A proper fraction is a fraction in which the numerator is smaller than the denominator. Proper fractions represent quantities less than 1. An improper fraction is a fraction in which the numerator is larger than or equal to the denominator. Any number over itself equals 1. Any number over 1 equals the number.
How many parts are in a fraction?
fraction consists of two numbers separated by a bar in between them. The bottom number, called the denominator, is the total number of equally divided portions in one whole. The top number, called the numerator, is how many portions you have. The bar represents the operation of division. The whole is divided into four equal parts.

Equivalent Fractions

Some fractions may look different, but are really the same, for example: It is usually best to show an answer using the simplest fraction ( 1/2 in this case ). That is called Simplifying, or Reducingthe Fraction

numerator / Denominator

We call the top number the Numerator, it is the number of parts we have. We call the bottom number the Denominator, it is the number of parts the whole is divided into. NumeratorDenominator You just have to remember those names! (If you forget just think "Down"-ominator)

Adding Fractions with Different Denominators

But what about when the denominators(the bottom numbers) are not the same? We must somehowmake the denominators the same. In this case it is easy, because we know that 1/4 is the same as 2/8: There are two popular methods to make the denominators the same: 1. Least Common Denominator, or 2. Common Denominator (They both work nicely, use the one you...

Part 1. Fraction as A Share

Let's imagine a whole pie divided into 4 equal parts. One part is shaded red. One red part out of four equal parts means 1/4of a whole is shaded. If we think of equal parts of a whole as shares, one share of a pie here is shaded red. The number 1 above the line is called a Numerator. It shows how many shares are shaded. The number 4 below the line ...

Part 2. Simplifying Fractions

Remember the pie from previous example? It had 3/6 of it shaded red. Let's add two new pies and look at them together. The first pie is divided into 4 shares and two are shaded red. But as we can see that's half the pie. The second pie is divided into 6 shares and three are shaded red. Half of the pie again. Finally, the third pie is divided into t...

Part 3. Comparing Fractions

When we see two pieces of a pie, we can usually tell which one is larger. Similarly with fractions, there is a simple way of comparing them to each other. Say we need to compare 1/3 and 2/7. Since they have different denominators, they have a different number of parts. So the First step must be to find the common ground. We do it by finding a commo...

Part 4. Adding Fractions

To add fractions, we again need to find a common denominator. Let's look at the following example. We need to add 2/7 and 3/9. The common denominator is 7 times 9 = 63. The next step would be to replace each fraction's own denominator with the common one. For the first fraction, 63 divided by 7 = 9 and 9 times 2 = 18. The result is 18/63. For the s...

Part 5. Subtracting Fractions

We'll start with two simple fractions. Subtract 1/3 from 3/5. As in the case of addition, we need to find a common denominator. So if we multiply our denominators, that equals 3 times 5 = 15. Next, we replace old denominators with the common one. Then we need to find our numerators. For the first fraction, 15 divided by 5 = 3 and3 times 3 = 9. The ...

Part 6. Multiplying Fractions

Suppose we need to multiply two fractions,2/5 times 3/7. The numerator of the product will be the product of the numerators of these fractions: 2 times 3 = 6. The denominator of the product will be theproduct of denominators of these fractions: 5 times 7 = 35. Thus, 2/5 times 3/7 = 6/35. If we need to multiply a fraction by a whole number, the nume...

Part 7. Dividing Fractions

To divide fractions, flip the divisor so its numerator becomes the new denominator and denominator becomes the new numerator. Then just multiply the fractions like we did before. For example, divide 3/7 by 2/5. After flipping, 2/5 becomes 5/2 and we end up multiplying 3/7 times 5/2 = 15/14. To divide fraction by a whole number, we invert that numbe...

Comment on fait pour calculer les fractions ?

Il faut d'abord réduire les deux nombres en écriture fractionnaire au même dénominateur. Ensuite, on additionne ou on soustrait les numérateurs et on garde le dénominateur commun.

Quelle est la fraction de 3 4 ?

Rappel : on appelle nombre entier, un nombre comme 0 – 1 – 2 - 3, - 4 – 5 - …. La fraction 4 est égale à 1 parce que le numérateur est égal au dénominateur. 8 4 u = 2 unités; on a 2 bandes partagées en 4 morceaux.
. La fraction 4 est donc égale à 2, c'est un nombre entier.
