Every thing falls back to basic.
If the fundamentals are weak, any maths learners will have a hard time moving forward in their maths learning journey.
Let me quote an example.
How do we change 4.75 to fraction.
We can use 475 / 100 and reduce it through long division. This will give 4 and 3/4.
However, if we know that 4.75 is actually consisting of 4 add to 0.75, the conversion will be simpler.
4 and 0.75 means 4 + (3/4) which leads directly to 4 whole and 3/4. Same as answer of above.
(NOTE: 0.75 is a quarter which equates to 3/4).
Simple isn't it?
Maths is interesting.
