Q: How are unit fractions different?

Write your answer...

Unit fractions all have the same numerators but the denominators can be different.

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

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.

Unit fractions are the fractions with numerator 1. the numerator is the part above of fractions ex 1/5,1 is the numerator

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

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.

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?

They are called unit fractions.

Dissimilar fractions have different denominators.

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.

Dissimilar fractions are fractions that have different denominators.

A unit = 1 = 1/1 in fraction form.

Well there are different kinds of fractions their are mixed numbers, regular fractions and improper fractionsThere are 5 kinds of fraction. Proper fraction, improper fraction, mixed number, unit fraction, and equivalent fractions. An example of a proper fraction is 3/4. An example of an improper fractions is 13/12. An example of a mixed number is 1 1/4. An example of a unit fraction is 1/3. An example of equivalent fractions is 4/8=1/2.I hope you like my answer... :)

unlike fractions

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.

Select a conversion factor so that canceling removes the undesired unit and leaves the desired unit.

a number then you add

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.

Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

Like fractions have the same denominator, unlike fractions don't.

its always going to be in the denominator of 2 fractions.

Yes they do
