Note: At time stamp@4:25 the mixed fraction example will be 5 3/4 instead of 5 4/3. So the improper fraction will be 23/4.

3.24 here 24 is now this can de done as (324-3)/99

We can convert 12.6934 where 34 is reccuring into fraction the same way we did for 0.17 where 7 is recurring @35:19.Here we will get (10^4)*x = 125665 + 1269.343434... =>9900x = 125665 = > x = 125665/9900.

It is correct if you mean 5*4/3 as 5 4/3.It is wrong if you mean 5*4/3 as 20/3.

Mixed fraction can be negative.But there are some rules while converting negative mixed fractions to improper fractions.Please refer to the following link to know about them:"http://mathforum.org/library/drmath/view/69479.html"
