Let p, q and r be the fraction such that p<q<r. If r is divided by p, the result is 5/2, which exceeds q by 7/4. If $$p+q+r=1{11\over12} $$ then what is the value of (r-p)?

Select the number that will come in place of the question mark (?) in the following mathematical statement.

$${5\over 9} \ of \ {11\over 14}\ 42\% \ of \ 540=?^2 -45 $$

Which of the following is largest fraction amongst $$ {5\over8}$$, $$ {3\over7}$$, $$ {2\over9}$$,  $$ {4\over5}$$?

If the differernce between the reciprocal of a positive proper fraction and fraction itself be$$17\over42$$, then the fraction is:

Find the least number which when subtracted from 10.000327 is a perfect square.

Simplify $$ {^3\sqrt {{4} {12\over {125}}}}$$.

The greatest fraction out of $$ {2\over 5},{5\over 6},{11\over 12},and \ {7\over8}$$ is
