How can you add similar and dissimilar fractions?
Adding similar fractions is easy, but adding dissimilar ones requires an additional step. Before you begin, you must know a few important key terms. First, the number on the top of a fraction is called the numerator, while the number on the bottom of a fraction is called the denominator. Similar fractions have the same denominator, also called a common denominator. To add dissimilar fractions (fractions with different denominators), you must first convert the fractions so that the denominators are the same.
What are the Rules of adding and subtracting dissimilar fractions?
If their denominators are different then find their lowest common denominator by means of their lowest common multiple remembering to adjust their numerators accordingly before adding or subtracting.
How is multiplying mixed numbers different than multiplying fractions?
if you have mixed numbers you make them into improper fractions before you multiply
How do subtract two fractions with different denominator?
First find the lowest common denominator and then adjust the fractions accordingly before subtracting the numerators
Before adding or subtracting two fractions they are converted into like fractions Explain with examples why this is necessary?
Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.
Before adding or subtracting Why are fractions turned into like fractions?
They have to have the same denominator.
Why crude oil is separated into different fractions?
Unless you own a cargo ship and run it on crude oil - some operators do - it has to be separated into fractions before it's usable.
Can you simplify before you divide fractions?
no
How could you eliminate the fractions before proceeding to solve this equation?
You can eliminate the fractions before proceeding to solve the equation to allow for easy factorization.
What must you do first before adding or subtracting unlike fractions?
you must make the fractions equivalent and with the same denomenator
How can you add up a fraction that have different denomanatrs?
Before you can do that, you have to put them all over the same denomanatr. That's why math classes work on common factors and common multiples before you get into adding fractions.
Why must you find a common denominator before adding fractions?
You can only add like to like. There is no mechanism for adding different types of fraction.
