Egyptian fractions were first used 3500 years ago.
what are the difference between the chinese writing system and the egyptian writing system
its just using fractions but not more than once to make other fractions
Different representation are better for different purposes.
It was different - the Egyptian system was pictographic and syllabic, the Phoenician one was alphabetic.
a number system based on ten, fractions and whole numbers, geometry to measure land, and the calendar.
i have o frikin idea i was just asking
Dissimilar fractions have different denominators.
* Hieroglyphic writing * 365-day calendar * number system based on 10 and fractions * medicine and 1st medicine books.
Dissimilar fractions are fractions that have different denominators.
Fractions are alike if they have the same denominators; otherwise they are different.
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.
Here is a setup of the Egyptian class system you out!
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.
Like fractions have the same denominator, unlike fractions don't.
Fractions whose denominators are different.
To subtract fractions with like denominators, subtract the numerators , and write the difference over the denominator. Example : Find 45−25 . Since the denominators are the same, subtract the numerators.
Unit fractions all have the same numerators but the denominators can be different.
Equivalent fractions are fractions that are the same amount but they have different numbers.
You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.
