Summary:
Before we get into the art of calculating with fractions, it is - as always - first you have to master the basics!
You should at least read and understand this short summary. Nevertheless, I also recommend to read the topic pages:
- they are entertaining and
- deepen your understanding.
You will have it easier later!
Page 1: A fraction - numerator, denominator, fraction bar
A fraction has a numerator, denominator and a fraction bar.

Page 2: Mixed Numbers
Page 3: Mixed Numbers to Improper Fractions
Page 4: Improper Fractions to Mixed Numbers
