2 nd one
ask why????????????????????
divide the denominator by nume. in both case , u get 2.00000
u will left with 200000/123420 and 200000/1234231 obviously 1 st one is greater than 2 nd so
1/(1 st one)<1/(2nd one)
Which one is greater 1234230/2468462 or 1234231/2468464 ?

no one!
This one is simple.. we have discussed something lke this even on a class IX-X problem
One of the first questions in Hall & Knight (Ratios)
Let us compare xy and x+1y+2
xy - x+1y+2 = x(y+2) - y(x+1) y(y+2) = 2x-yy(y+2)
so, the sign of xy - x+1y+2 depends on 2x-y
here x= 1234230 and y = 2468462
2x = 2468460 < y
so, 2x- y < 0
=> xy - x+1y+2 < 0
=> xy < x+1y+2
=> first fraction (of question) < second fraction (of question)
