@oyely: if you have 10x = 1.667 then how can you write 9x = 1.5003?

Oyely said:   1 decade ago
Guys i've found a simple method.
u can covert it like x=.1667 and 10x=1.667=>9x=1.5003 so x=1/6
similarly for y=0.6667=> y=2/3
and 0.8883=1-0.1667=>1-1/6=5/6
now it's easy method to solve this problem.

hope,it will help u to solve this problem.

@Rakesh:
0.1667 is equivalent to (16-1)/90(by RECURRING DECIMAL) we get 1/6. 5/6 is equal to (83-8)/90.
