What are like and unlike fractions?
Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
How do you solve all fractions problems?
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.
Fractions can be added and subtracted only if they're fractions?
We can only add or subtract fractions if they have the same denominators
Define equivalent fractions?
Equivalent fractions are fractions that have the same value as another fraction.
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.

How are Egyptian fractions different from your system of fractions?
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.

What is the significance of the Horus eye fractions in ancient Egyptian mythology and culture?
The Horus eye fractions, also known as the Eye of Horus, were symbols of protection, healing, and power in ancient Egyptian mythology and culture. They were believed to bring good luck and ward off evil spirits. The fractions represented different parts of the eye, each with its own meaning and significance. The Eye of Horus was also associated with the god Horus, who was a symbol of kingship and protection in Egyptian mythology. Overall, the Horus eye fractions held great importance in ancient Egyptian beliefs and rituals.
How do Egyptian fractions work?
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.
What were the Egyptian contributions to other civilizations?
a number system based on ten, fractions and whole numbers, geometry to measure land, and the calendar.
What is the significance of the Eye of Horus in ancient Egyptian fractions?
The Eye of Horus was a symbol used in ancient Egyptian fractions to represent different parts of a whole. Each part of the eye represented a specific fraction, making it easier for the Egyptians to perform calculations and measurements. This symbol helped them in various aspects of daily life, such as building, trade, and agriculture.
What are some examples of ancient Egyptian medical advances?
* Hieroglyphic writing * 365-day calendar * number system based on 10 and fractions * medicine and 1st medicine books.
What are like and unlike fractions?
Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
