If x = 0.rstu, where r, s, t, and u each represent a nonzero digit of x, what is the value of x?

1) r = 3s = 2t = 6u

2) The product of r and u is equal to the product of s and t.

Thats the only combination where all the digits (rstu) are less than 10.

From B: we do not get anything!

3x2 =6x1 and also 3x4=2x6!
