Raju ate $$3\over 8$$part of a pizza and Adam ate $$3\over 10$$ part of the remaining pizza. Then Renu ate $$4\over 7$$ part of the pizza that was left. What fraction of the pizza is still left?

The numerator of a fraction is 3 more than the denominator. When 5 is added to the numerator and 2 is subtracted from the denominator, the fraction becomes $$8\over 3$$ . When the original fraction is divided by$$5{1\over 2}$$, the fraction so obtained is:
