Fractions are a necessary part of maths.
They come in many forms; improper, proper and mixed number.
Though improper and proper forms are direct in its presentation and interpretation, mixed number form may pose a potential mistake for young learners.
Example:
Is this 2 + (3/4) or 2 x (3/4) ?
Caution has to be taken to stress it as 2 + (3/4).
Some students have taken it to mean 2 pieces of (3/4) !
Dangerous isn't it.
But rest assure.
If you understand the language of maths and its "grammar", all will be well and interesting.
