Pre-Algebra 11 - Fractions and Rational Numbers

The first fractions used by ancient civilizations were "unit fractions". Later, numerators other than one were added, creating "vulgar fractions" which became our modern fractions. Together, fractions and integers form the "rational numbers".

Brilliant! Thanks so much for this excellent Maths video, perfect for younger students to get exposed to some really fundamental but hard to explain concepts.

Animated maths really kicks asses. I mean it is really good way to express the idea behind mats. Most teachers just saying stuff and you have to visualise like you can. With this lecture it really open minds that something is shown as a line. I know it is simple stuff but it very interesting to see.

I am an Egyptian and this is the first time to hear about what is called "Egyptian Fractions", thanks..

Your video series is fantastic. I do have a question though... I'm wondering why we are using the letters "p" and "q" to represent the numerator and denominator respectively instead of something more memorable, like "n" and "d". I'm assuming there is a specific reason behind this convention and that it will become apparent later, but I am curious...

The Mathematics behind the scenes is beautiful ❤

The only problem is the graphic representation on the number line : O is not zero but the supposed Origin and the point 1 is neither a point nor one but the supposed End ; the whole distance is a Unit.

Here is a tip:
Natural numbers are Fractions. The denominator of the fraction is 1.
Example:
5 = 5/1

Also, in a fraction, can the numerator exceed the denominator?

Please reply - Can fractions be negative...I'm confused about this concept!
