Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.
We can only add or subtract fractions if they have the same denominators
Equivalent fractions are fractions that have the same value as another fraction.
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.
Egyptian fractions were first used 3500 years ago.

Well as a matter of fact Egyptian fractions can only be unit fractions with different denomitnators. They will never do 1/2+1/2=1 instead they would us the mehod /i explained.

The idea behind Egyptian fractions is to write any fraction as the sum of unit fractions which are fractions with the number 1 in the numerator, like 1/2 or 1/3. The catch is all the fractions have to be different. This means no two fractions with the same denominator can be added. So we write 2/3 but that is not a unit fraction. You cannot write it as 1/3+1/3 using Egyptian fractions because the violates the repeating the fraction rule. Saying 3/4 = 1/2 + 1/4 is totally OK. The reason they are worth understanding and studying, other than their pure beauty, is they allow you to compare fractions easier than our current system. They also allow you to divide things up into parts more easily than our current system. So since we cannot write 2/3 as 1/3 + 1/3 how do we write it? We write it as 1/6 +1/2. One common notation for this Egyptian fraction is [2,6]. Using this notation, here are a few others: 2/3= [2,6]2/5= [3,15]2/7= [4,28] Now that you see what they are, let me explain what I meant about dividing and comparing. If I write 5/8 as 1/2+1/8 and I want to divide 5 things among 8 people, each would get 1/2 and 1//8. That is 5/8 and 8 ( 5/8)=5 . It is as simple as that. In general if I have m things to divide among n people, I write m/n as an Egyptian fraction and each person gets that fractions worth of the thing I am dividing. When we compare fractions we usually have to either convert them to decimals or create fractions with a common denominator. With Egyptian fractions, this is not necessary. You write the numbers as Egyptian fractions and then keep doing that with the fractions you have until you can compare the two. You get the added advantage of seeing just how much bigger or smaller one number is from the other.
