Hi,

Re TY, As to options for your son's math tutoring, understand what you mean, 

an answer is not worth much..if the student is left with no understanding 

as to how to do a similar problem on their own. Wished I lived next door :)

Do think a local private tutor is the best option for math, as it is best done with pencil and paper.  

This volunteer site does has many capabilities for simulating that the  work was done with 'paper'/pencil, 

which is great...but know of no others like it. 



If...

5%2F4+=+%2810%2F16%29n

%2816%2F10%29%285%2F4%29+=+%2816%2F10%29%2810%2F16%29n  |multiplying each side of EQ by 16%2F10

  4%2F2+=+n

   2 = n

and..

5%2F4+=+%2810%2F16%29%2A2+=+10%2F8+=+5%2F4



If...

5%2F4=10%2F%2816n%29   | Cross Multiplying to solve

  80n = 40

    n = 40/80 = 1/2
