What is a Fraction?
A number ususally expressed in a form a/b. A fraction has a numerator and a denominator. The numerator is the number on top of the and shows how many parts you have. The denominator is the number at the bottom and it shows how many equal parts there are in the whole.
Now that you know what a fraction is, you should also know the different kinds of fractions there are. The different kinds of fractions are proper, improper and mixed. A proper fraction is the one I showed above^^.
An improper fraction is when the mumerator is larger than the denominator. An example would be 5/3. You could convert them into mixed fractions. A mixed fraction is a whole number and a fraction combined. An example would be 1 2/3.You convert mixed fractions into improper fractions by multiplying the denominator with the whole number and adding the numerator. The result would be the numerator and the denominator stays the same as the denominator of the mixed fraction.
Adding and Subtracting Fractions
To add fractions, you have to make sure that you have the same denominator. If you don't then use just find the least common multiple of the denominators or you cross multiply.
To subtract fractions have the same steps as adding fractions, instead you subtract.
Here are my questions.
Multiplying fractions is really simple. All you got to do is to multiply the numerators and multiply the denominators. Then simplify.
Here are 2 examples.
Here a lot of ways to multiply fractions one way is to multiply the first fraction the second fractions reciprocal. You could also use the secret fraction solving tool called the Ratio Table. It works every time.
This is how you divide proper fractions.
Second picture:This is how you divide mixed fractions.Word Problems
Sorry if I made any mistakes.
