They have the same numerator (1) but different denominators. Since the numerator is 1 in each fraction, it cannot be simplified therefore each unit fraction is in its simplest form. Then, because the denominators of any two of them are different the fractions must be different.

The answer depends on what they are meant to be alike and different from!


Is it true that ancient Egyptians thought that all fractions could be written as unit fractions?

No. They thought that all fractions could be expressed as combinations of unit fractions. They and other ancients may have thought that any fraction could be wretten as a combination of unit fractions, but according to wikipedia they (ancient Egyptians) had special symbols for 2/3 and 3/4 and even had a papyrus used by scribes that listed the equivalents for 2/n, so they did not always write fractions as this combination of unit fractions. Does your question mean a combination of unit fractions, or as a unit fraction?


How are unit fractions alike?

All of them have a numerator of 1.


How is a unit fraction different from a fraction?

A unit fraction IS a fraction, but of a specific type where the numerator is 1. Thus 1/2, 1/3, 1/4, etc are all unit fractions.


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.


How do you do unit fractions?

How would we do it well remember a unit fraction always has one as a numerator. So 2/3 would be 1/3 plus 1/3. These are the unit fractions. It's got a 1 is a numerator all right 5/6 would be a 1 6.


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.

What other n number of unit fractions can be found that sum to 1?

There are infinitely many different ways to make groups of fractions that sum to 1.


Can any fraction be expressed as the sum of two unit fraction?

Yes, but only if negative unit fractions are included.For example 3/7 = 1/2 - 1/14but I do not think there are positive unit fractions that will do.Yes, but only if negative unit fractions are included.For example 3/7 = 1/2 - 1/14but I do not think there are positive unit fractions that will do.Yes, but only if negative unit fractions are included.For example 3/7 = 1/2 - 1/14but I do not think there are positive unit fractions that will do.Yes, but only if negative unit fractions are included.For example 3/7 = 1/2 - 1/14but I do not think there are positive unit fractions that will do.
