Question 1164487
I believe you mean this:
----------------------------------------------
If a fraction is divided by 1 ¼ and <s>them</s> THEN
THAT IS subtracted from 2 ½ gives the result
of 1 7/10, what is the value of the
fractions?
-----------------------------------------------


R, the fraction wanted
{{{highlight_green(2&1/2-R/(5/4)=1&7/10)}}}----------Solve for R.




--------No.  Not this.  Mistaken Interpretation is below-------------
---------------------------------------------------------------------


R, the fraction, ratio of two numbers


{{{R/(1&1/4)=R/(5/4)=(4/5)R}}}



"Them", would be  {{{R}}} and {{{(4/5)R}}}.



"them subtracted from  ,..."  would become
{{{2&1/2-R-(4/5)R=1&1/7}}}-------------------simplify and solve this for R.
