Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.

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.
What fractions are equivalent to?
Fractions can be converted to decimals, percentages or mixed numbers.
How can you convert to proper fractions?
It depends on what you want to convert to proper fractions. Not all things can be converted to proper fractions.
How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract
What is 14.4 converted into fractions?

Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.
Why do you convert unlike fractions?
Unlike fractions have denominators that are unequal, and therefore cannot be added or subtracted. If two fractions need to be added or subtracted they must first be converted to like fractions.
What is the same about two fractions that are like fractions?
Fractions that are equivalent have the same values when simplified.
What fractions are equivalent to?
Fractions can be converted to decimals, percentages or mixed numbers.
Should all improper fractions be converted to mixed fractions?
Yes they should
What is the relashionship between fractions and decimals?
The relationship between fractions and decimals can be seen as follow. Fractions can be represented as ratio of two numbers and on dividing can give a decimal value. And decimal value can be converted into a fraction too.
LCD of two or more fractions mean?
LCD is the Lowest Common Denominator which is the lowest number into which the denominators of all the fractions will each divide exactly. Each of the fractions can then be converted to an equivalent fraction with the new denominator which then allows the fractions to be added and/or subtracted.
How is adding like fractions and adding unlike fractions the same?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
