1 Fractions are parts of whole numbers or integers
2 Fractions have a numerator above a denominator
3 Fractions have a solidus line that separates numerator from denominator
4 Fractions can be common as for example 3/4
5 Fractions can be improper or 'top heavy' as for example 22/7
6 Fractions can form the part of a mixed number as for example 3 and 1/7
7 Fractions can be converted into percentages: 1/2 = 50%
8 Fractions can be converted into decimals: 3/4 = 0.75
9 Fractions can be equivalent: 5/8 = 10/6
10 Fractions need a common denominator when added or subtracted
11 Fractions are easily multiplied or divided without a common denominator
12 Fractions are rational numbers
13 Fractions can never ever be Irrational Numbers
14 Fractions are turned into decimals by dividing the numerator by its denominator
15 Fractions can be turned into improper fractions from mixed numbers
16 Fractions are used in algebra and trigonometry
17 Fractions are used in converting Celsius into Fahrenheit
18 Fractions can be changed into scientific notation: 1/5000 = 2.0*10^-4
19 Fractions are in their lowest terms when their HCF is one
20 Fraction derives from a Latin word meaning to break apart
21 Fractions are used in the Roman numeral system to a limited extent as for example S = 1/2
See related question: 'What are 15 or more facts about fractions'
Yes their is an interesting fact about fractions that is you have to know how to do them
it has a numerator
If the system is truly forgotten then nobody will remember even one fact about it - leave alone a score or more!
to make them as simple as possible

I suggest you take a look at the Wikipedia article on "triangle", or at some similar source. I am sure you can find lots of interesting facts there.

I can get you started with one: Nobody who knows anything about it calls it "the pi of a circle". Pi is pi.
its just using fractions but not more than once to make other fractions
