Questions for Learner :
1. How do we add two fractions of the same/common denominator ?
2. Explain the idea of equivalent fractions
3. How do we add two fractions with different denominators ?
4. How do we find the "right" number of parts to split, so that the parts
in both fractions are of the same size ? (From this we get
the same/common denominator for both fractions)
